Currently, when postmarketOS fails to boot up, retrieving any
information necessary to root cause the issue is non-trivial, requiring
building a custom initramfs with debug-shell enabled and then manually
copying out data.
Let's improve the situation by exporting logs automatically on boot
failure. This is safer than just exposing a root shell but still
provides a whole lot of useful info that should make duplicating and
triaging issues much easier for developers.
This commit implements the functionality and includes some generally
useful data. We then generate a README and expose files for each command/log
as well as an archive that can be easily attached to a GitLab issue.
To help with triaging, also record the version of the postmarketos-initramfs
package and hash the init.sh and init_functions.sh files.
For testing purposes, you can trigger the log recovery mode on-time by
creating an empty file named ".pmos_export_logs" in the /boot partition.

With the recent changes in commit 80fff9242, it's possible that the
client IP address is customized. Use the same code as in
init_functions.sh to get the this potentially customized IP address to
use for the nbd-client.

Since the original "Loading..." splash is being shown before the hooks
is being run, we should go back to the "Loading..." splash once we're
done in the hook.
