media: Adjust for new header Android.bp requirements

 * nativebase headers are now packaged in a header library,
   so just include that for libOmxVdec
 * nativewindow headers cannot be included without building
   libnativewindow, so add that as a shared library to
   libstagefrighthw and libOmxVenc, which includes some of
   libstagefrighthw and must have libnativewindow as well
