feat: profile amiberry 5.6.5 built by ROCKNIX

ROCKNIX builds amiberry 5c54536 (target.h declares 5.6.5). Every file
it reads lies below its start path, the working directory: the ROM
database dumps, aros-ext.bin, aros-rom.bin and rom.key in kickstarts/,
the WHDLoad booter files in whdboot/. Profiled from that revision,
pin_frozen with pin_build on ROCKNIX's package.mk.

The ROCKNIX scraper records the folder its start script enters and the
kickstarts link it carries there by copying /usr/config/amiberry, so
<cwd>/kickstarts binds to the BIOS root. A standalone + libretro profile
under a name the platform's own build answers to no longer resolves
there: ROCKNIX's amiberry is 5.6.5, not 8.5.0.
