Empty bfcache's android_browsertests and content_shell_test_apk filters.

I'm not deleting them because the set up is a bit complex and we can just
leave them empty and ready to use if needed for now.

All tests pass when built with is_component_build=false.

android_browsertests
https://chromium-swarm.appspot.com/task?id=480617e093827910

content_shell_test_apk
https://chromium-swarm.appspot.com/task?id=48062ebc37df7010

chrome_public_test_apk
https://chromium-swarm.appspot.com/task?id=48059c46554c9d10

content_browsertests is more complex and will come in a later CL.
