Instead of renaming the boot entries to the new naming scheme
update existing ones by making `ostree admin kargs edit-in-place`
to use the old naming scheme.
Resolves: #RHEL-58437
A new naming scheme for boot entries was introduced in
version 2014.5 [1]. We need to rename the old ones to this
new scheme before running `ostree admin kargs edit-in-place`.
Otherwise, the updated bootloader configuration will be written
to a new file instead of updating the existing one making the
system not bootable.
