Same as $KERNEL_INSTALL_BYPASS, but for hwdb. This will speed up
cross architecture image builds in mkosi as I can disable package
managers from running the costly hwdb update stuff in qemu user
mode and run it myself with a native systemd-hwdb with --root=.
Previously, true by validate() means several configs are outdated and we
need to reload configs. That's not intuitive for me. Let's rename the
functions.
Currently, the systemd-hwdb --root flag only has an effect for the
'update' verb. It would be useful to be able to use the --root option
for the 'query' verb too (e.g. for testing a hwdb.bin created with
systemd-hwdb update --root <path>).
Use sd_hwdb_new_from_path to initialize the hwdb if --root is passed to
systemd-hwdb query.
Note that this functionality was not added to 'udevadm hwdb' since that
command is deprecated.
