This change renames the various patch files to reflect that they are
based on diffs against MAAS 2.8. Files that were previously listed as
2.3_*.patch originally were created against MAAS 2.3, but this is not
particularly relevant anymore.

MaaS 2.3.5 added bios grub partition changes that no
longer cared for the size of the storage device nor
whether it was a boot device. This patch effectively
restores the original behavior which was also
reintroduced in MaaS 2.4.0.
