Subject: [PATCH] fix(dracut-install): do not fail when SOURCE is optional and
 missing

When running dracut-install with '-o' (optional source), and nullglob
at the same time, when all of the arguments evaluate <null>, dracut-install
should not fail even when the source is not specified.

Resolves: #2047654
