fix: improve hostonly sloppy mode

Sloppy mode is the original hostonly mode.

Strict mode was newly introduced much later in 2018 (v048) as a non-default
opt-in special optimization mode to allow modules to ignore more drivers
or do some extra job to save memory and disk space, while making the image less portable.

This PR includes more dracut modules (and with that more kernel modules) in sloppy mode.
