feat: name elec and knulli builds in profiles

EmuELEC, AmberELEC and KNULLI launch standalone emulators by the name
their launch code dispatches on (HATARISA, PPSSPPSDL, FBNEOSA) and ship
32-bit or patched builds of libretro cores under their own .so names
(flycast_32b, mupen64plus_next_alt, genesis_plus_gx_cart_special,
mame0139, flycast-xtreme). Each name joins the profile of the project
its package builds. fceumm_mod reads gg.rom, not gamegenie.nes, and
never opens it, so it gets its own profile.
