Specifically the test GeolocationPermissionContextTests.GeolocationStatusSystemDisabled fails when run alone.

That is, this passes:
python build/android/test_runner.py gtest --suite unit_tests --output-directory out/Release -v

And this fails (same chrm rev):
python build/android/test_runner.py gtest --suite unit_tests --output-directory out/Release -v -f GeolocationPermissionContextTests.GeolocationStatusSystemDisabled

The test complains with:
I   39.554s Main  1 failed tests remain.

This will block us from arbitrarily sharding all android test suites. The test was added in https://codereview.chromium.org/2743603002, so assigning to author.
