chore: merge the amberelec, emuelec, knulli lists

AmberELEC, PAN4ELEC and EmuELEC detection now installs their own lists
at /storage/roms, the root those lists are written against; KNULLI its
own list at /userdata/bios. JELOS, KOLOS, UnofficialOS and Arch R keep
RetroArch's list with the folder their retroarch.cfg names.
