Build libmedia_native module in order to get mediaserver running

Libcameraservice.so relies on libmedia_native.so so it will not start without libmedia_native.so. Mediaserver relies on libcameraservice.so so if libcameraservice.so isn't working then mediaserver will not work and thus the ROM will not boot.
