Fix FFMPEGMediaPlayer: Use GL_ALPHA (texture format intern/data) instead of GL_RGBA/GL_ALPHA ; Load dedicated native libav/libffmpeg

- ES2 spec does not allow GL_RGBA/GL_ALPHA.

- Load dedicated native libs (libav/libffmpeg) since distributions don't create
  symlink e.g. libavutil.so -> libavutil.so.53
