Revert of Run android tests through runtest.py.

Revert of Run android tests through runtest.py. (https://codereview.chromium.org/414383002/)

Reason for revert:
Looks like the cause of http://build.chromium.org/p/chromium.linux/builders/Android%20Tests%20%28dbg%29/builds/22085 failing.

runtest.py was repeatedly unable to find the test targets it was supposed to run.
