Rebuild boot images the Plymouth migration left stale

Browse Source 
1784917531 gated its UKI rebuild on initramfs_async=0 being present in
the Limine config, but omarchy-settings ships omarchy-defaults.conf with
that parameter already in it. Any machine that installed the package and
ran the migration in the same update matched the config the package had
just written, skipped the rebuild, and kept booting an image baked
before the config existed — without initramfs_async=0, so encrypted
boots still fell back to an unthemed text LUKS prompt. Compare the
booted command line against the configured one and rebuild when they
disagree.

# already in it. On a machine that installed the package and ran the migration
# in the same update, the guard matched the config the package had just

# line — including initramfs_async=0, so Plymouth still loses the LUKS prompt.
