Split P8 and P9 Hostboot and OCC packages

This was causing a couple of issues:
1) increased complexity in build files
2) It breaks the pkg-version patch detection/checksum
3) Failing to apply patches to would silently fail

The split makes this a bit easier and requires less custom code.

We keep the P9 hostboot/occ named hostboot/occ, so that day-to-day,
nobody notices a difference. The only difference you'll notice
is if doing POWER8 hostboot/occ development, as the package name
will be 'hostboot-p8' or 'occ-p8'.
