Steve Baker 8059a59583 Make centos reset-bls-entries behave the same as rhel
This makes 03-reset-bls-entries consistent with rhel so that the glob
match is *.conf, and a check is added to ensure that a rename is
actually required.

# This is a workaround for the grub issue reported upstream with

# This renames the BLS entries from the upstream .qcow2 image in
# /boot/loader/entries with the current machine-id. This means that in the
# bootloader setup, grub2-mkconfig will update config options as required.
