Subject: [PATCH] feat: profile the MAME releases recalbox builds

Recalbox ships libretro/mame built at 0.258 and at 0.278, and no
profile described either release. mame_hash_scraper gains --release,
which reads the BIOS root sets at one mamedev tag and writes a profile
pinned to it; mame0258 and mame0278 are generated from it, every
source_ref anchored at its tag.
