_FILE_OFFSET_BITS=64 support for asset_manager.h.

Browse source 
Rename off_t based functions to their 64-bit equivalents if we're in
LP32 with a 64-bit off_t.

We can safely do this for all supported API levels now since API 13 is
no longer supported. Clean up all the guards for that API level while
I'm here.

Test: make checkbuild
