Steve Baker f118649738 Fix BLS entries for /boot partitions 
Creating a separate /boot partition is desirable in some cases[1].
This change detects if /boot is a partition, and ensures that the
kernel/ramdisk paths are correct in either case. This is applied to
all BLS entries files, whether they were generated by the previous
grub2-mkconfig call or in the source image.

This means the rhel9 specific workaround can be removed since all
paths are now normalised at this stage.
