Add dummy Android test APK to be used for buildbot automation testing.

Until we have WebRTC test targets created for Android, this test
makes it possible to move forward for buildbot automation.

TEST=Android NDK buildbot and local execution of:
source build/android/envsetup.sh
gclient runhooks
ninjar -C out/Debug
verified the out/Debug/simple_apk dir exists and has the files.
