Code Issues Proposed changes

Call grub2-mkconfig with --update-bls-cmdline

Browse Source 
Recent versions of redhat grub2-mkconfig no longer automatically update
kernel arguments in BLS entries[1]. This change optionally adds the
--update-bls-cmdline argument where supported so this previous
behaviour continues to work.
