[resultdb] enable resultdb for junit_tests on andriod,clang at 50%

ResultDB for junit_tests was enabled on chromium.android at 30%, and
100% of the builds succeeded with resultdb.
https://screenshot.googleplex.com/BvHH2VDXm7hGvCh

There are only 3 builder groups with junit_tests in chromium.
- chromium.fyi
- chromium.android
- chromium.clang

If all builds on android and clang succeed after this CL, the next CL
will enable ResultDB for junit tests on all builders at 100% rate.
