Delete temporary local AHardwareBuffer definition

While waiting for a newer ndk, some constants and types
were locally declared. Since January there is an NDK that contains
those types so the local declarations are not needed anymore

In some jumbo builds the local and ndk declaration clashed so it
is time to drop the local declarations, but keeping some types
still needed by the dynamic lookup of some (to be public) internal
functions.
