Some follow-up checks of recent firmware fixes caused me to realize
we've mixxed up the firmware cleanup even more and our defensiveness
on the removal resulted in some confusion.
Ultimately, I guess this is... my second attempt to improve this, but
also attempt to heavily restrict our automatic glob expansion usage.

The net result before this change was the IPA Centos10 build initramfs
files were running around 533 MB, and with this change the file sizes
are down to 464MB.
