Android: install codecs as native libs instead of extracting them (FS#12134).

Browse source 
Codec files are loaded as dynamic libraries. Instead of extracting them from
the packaged libmisc.so and therefore having them present twice on the device
put them into the apk as native libraries. Decreases the size of the installed
Rockbox by the compressed size of the codecs. Also, the extraction on first
Rockbox startup gets notably faster since it's less data to extract.
