Fix 'Android Tests' build bot.

By default, build/android/run_tests.py looks for files under out/Debug/,
which will fail when in Release builds. One has to add the --release
flag when invoking the script.

Introduce internal function _bb_android_run_tests to always invoke
the script with the right flags, and ensure all clients use it.

+ Add the same flag to Release build when invoking instrumentation_tests.py
