Add Android.bp.

Symlink include/gsl to gsl so we can expose the headers without
exposing the entire directory.

Test: We can't build their tests yet (import of the unittest library
      is pending approval), but I made a quick test program to make
      sure `gsl::not_null` was working as expected. I've also run
      `ctest` after building for Linux, so we can at least be sure
      that it at least works outside our build system.
