package/rpi-firmware: fix missing files in overlays

Browse Source 
When supporting multiple hardware targets, overlay_map.dtb might
be needed to map overlay names to one of several implementations [1].
If the correct overlay names are specified in config.txt, the map file
is not needed, but it also doesn't hurt.
