vba_m carried md5 values taken from docs.libretro.com while its entries
declare validation: [size], which is what src/gba/GBA.cpp:3262-3272 and
src/gb/GB.cpp:2172-2192 actually check. Only the source decides a hash,
so they are gone.
The profile becomes an alias of vbam, and the buildbot name vba-m moves
into its cores: list so target filtering still resolves it.
libretro_scraper: EXTRA_ARCADE_FILES adds namcoc69/70/75, msx, qsound
to arcade system. segasp.zip added to dreamcast-arcade. ep128emu
includes injected for enterprise system.
new profiles: vba_m (GB/GBC/GBA with doc vs source notes),
beetle_gba (Mednafen GBA).
