Clean up Android.mk.

- Move away from the deprecated LOCAL_COPY_HEADERS to
  LOCAL_EXPORT_C_INCLUDE_DIRS.
- Remove unnecessary additional dependencies on Android.mk since
  the build system now does this by default.
- Remove unnecessary hardcoded include paths for dependencies that
  set LOCAL_EXPORT_C_INCLUDE_DIRS.
