03-reset-bls-entries was previously a pre-install script to run after
the machine-id was set, but a new kernel may be installed during the
install phase, which will install another bls entry file with a
filename which differs from the machine-id.
This means this package installed bls file won't be updated when
grub2-mkconfig is called, resulting in incorrect kernel args and boot
device in the entry file that will get booted by default.
By fixing the filenames after the new kernel is installed,
grub2-mkconfig will update the bls file that actually gets used on
boot.

Similar to the CentOS-9-Stream fix [1] this change renames the default
BLS entry to match the current machine-id so that grub2-mkconfig calls
will refresh the kernel options.
However there is an additional issue with the rhel-9 base image. It is
unique in having a dedicated boot partition, so the path to the kernel
and initramfs don't include /boot. This results in an unbootable image
when /boot is a directory of the root partition.
These paths do not get corrected by calling grub2-mkconfig, so this
change performs a sed on the paths to fix them for a root partition
/boot.

Per the inline comment, a machine-id is required for kernels to
install correctly (this may well be a bug, but the linked issue
remained inconclusive).
Add a call to make the machine-id before install packages.
