Quadruple monitor table size in debug build

The monitor table in Android debug builds was intentionally very small,
so that we could test expansion to more than a single level. This has
become problematic since debug builds are increasingly used to run
frameworks tests.

As a compromise, increase the size by a factor of 4. This is still a
factor of 64 smaller than production builds.
