Restructure the supervisor image to remove the dependency on the custom `alpine-supervisor-base`
image and the custom node build. The dockerfile is now a multi-stage
build that splits the process into two build stages and two runtime
stages.
Here is the full list of changes
- The node binary is now copied from `balenalib/${ARCH}-alpine-node:12-run`, the node binary
now supports running with a debugger.
- The runtime image now inherits from the official `alpine:3.16` image
- Tests are ran within the runtime image configuration instead of the
build image
- Livepush is ran within the runtime image context
- Unnecessary packages have been removed
- Removed avahi-daemon.conf as that service is not being used
- Fix livepush to work with a multi-stage image. This also deprecates the `image-tag` argument to npm run sync as
`SUPERVISOR_TAG` is no longer used by new OSs
- Fix livepush build on old rpi devices. Allows passing a 'PREFIX'
argument to let the builder pull images directly from docker hub arch
repositories. Relates to https://github.com/balena-os/balena-engine/issues/269

Some libraries, like [proper-lockfile](https://www.npmjs.com/package/proper-lockfile)
use directories instead of files for locking. This PR allows the supervisor to be able to
work with those types of locks when lock override is requested.
Closes: #1978

Host config shouldn't be tied to applications in the first place, but
needs to be done so because it uses update locks to determine when it's
safe to patch host config, and update locks are tied to apps.

There is no functionality which 1) stores the filesystem lock status when toggling override
to on, and 2) restore the system to that status when toggling override to off.

We don't need to read the host's hostname through /mnt/root/etc/hostname,
because the hostname is written to config.json on a change. When the hostname
has never changed, it won't be found in config.json, so we can default to
the Supervisor container's /etc/hostname as it will match the host's
/etc/hostname, the network mode being `host`.

This fixes a race condition that could occur with the first current
state report, where if the device managed to send the current state
report first, then the device name on the cloud would be set to `local`
(see #1959).
