Build 32- and 64-bit Android mojo_core for Chrome OS distribution

Causes Chrome builds for Chrome OS to emit additional 32-bit and
64-bit copies of the mojo_core shared library built against the
Android toolchain, for use from within the ARC++ container.

In order to support building these library targets, this also
modifies DEPS to include a minimal set of required Android support
tools and libraries in chromeos checkouts.
