Fix TimeFormat tests and enable them on Android

The test is flaky/failing apparently because FromLocalExplode is flaky.
Use FromUTCExplode and the fixed timezone (America/Los_Angeles)
instead of the default timezone of wherever the test runs.

Bug: 671429, 582915
Test: base_unittests --gtest_filter=TimeFormat*
