Move FilePathWatcher tests to base_unittests.

A long time ago, they had been moved to browser_tests. This was
because of the OS X implementation was flaky and caused hanging tests,
and the absence of robust test timeouts in unit tests resulted in the
entire test binary hanging.

Things have changed significantly meanwhile: The new test launcher
provides robust test timeout handling, and the OS X implementation has
been fixed. Hence, it's safe to move the test over to base_unittests.
