system: move sd_booted implementation to os abstraction
This implements lazy loading of the systemd marker (they are not accessed in init and shim) and ensures consistent behaviour when running with a stub.

app/seal: symlink /etc entries in permissive default
test / test (push) Successful in 20s Details
Fortify overrides /etc/passwd and /etc/group in the sandbox. Bind mounting /etc results in them being replaced when the passwd database is updated on host.

internal: wrap calls to os standard library functions
test / test (push) Successful in 19s Details
This change helps tests stub out and simulate OS behaviour during the sealing process. This also removes dependency on XDG_RUNTIME_DIR as the internal.System implementation provided to App provides a compat directory inside the tmpdir-based share when XDG_RUNTIME_DIR is unavailable.

fmsg: produce all output through fmsg
test / test (push) Successful in 17s Details
The behaviour of print functions from package fmt is not thread safe. Functions provided by fmsg wrap around Logger methods. This makes prefix much cleaner and makes it easy to deal with future changes to logging.

app: move wayland mediation to shim package
test / test (push) Successful in 29s Details
Values used in the Wayland mediation implementation is stored in various struct fields strewn across multiple app structs and checks are messy and confusing. This commit unifies them into a single struct and access it using much better looking methods.

app: move app ID to app struct
App ID is inherent to App, and it makes no sense to generate it as part of the app sealing process.

app: port app to use the system package
This commit does away with almost all baggage left over from the Ego port. Error wrapping also got simplified. All API changes happens to be internal which means no changes to main except renaming of the BaseError type.

helper/bwrap: ordered filesystem args
The argument builder was written based on the incorrect assumption that bwrap arguments are unordered. The argument builder is replaced in this commit to correct that mistake.

app: remove bubblewrap launch method
Launch methods serve the primary purpose of setting UID in the init namespace, which bubblewrap does not do. Furthermore, all applications will start within a bubblewrap sandbox once it has been implemented.

app: clean up interactions and handle all application state and setup/teardown
There was an earlier attempt of cleaning up the app package however it ended up creating even more of a mess and the code structure largely still looked like Ego with state setup scattered everywhere and a bunch of ugly hacks had to be implemented to keep track of all of them. In this commit the entire app package is rewritten to track everything that has to do with an app in one thread safe value.

In anticipation of the client/server split also made changes:
- Console messages are cleaned up to be consistent
- State tracking is fully rewritten to be cleaner and usable for multiple process and client/server
- Encapsulate errors to easier identify type of action causing the error as well as additional info
- System-level setup operations is grouped in a way that can be collectively committed/reverted
  and gracefully handles errors returned by each operation
- Resource sharing is made more fine-grained with PID-scoped resources whenever possible,
  a few remnants (X11, Wayland, PulseAudio) will be addressed when a generic proxy is available
- Application setup takes a JSON-friendly config struct and deterministically generates system setup operations
