feat: profile amiberry 8.0.0 built by EmuELEC

EmuELEC 4.8 builds amiberry 452783a (CMakeLists.txt declares 8.0.0).
Same paths as 7.1.1, a ROM database with the PPC flash images, which
the scan hashes with their config bytes cleared, so no file hash is
declared for them. Tests check that ROCKNIX, AmberELEC and EmuELEC
resolve their own build, the other platforms the 8.5.0 profile, and
that ROCKNIX places its kickstarts at the BIOS root.
