Remove gtest and boringssl from android unit test build script

Merge of http://go/wvgerrit/16300

This CL removes gtest and boringssl from
build_and_run_all_unit_tests.sh.  Instead, we change each "mm"
to "mm || mma".  Thus, if mm fails, we assume it is because of a
missing dependency and try mma which builds all dependencies.
