cros_test_lib: use better names in test output

The current test output looks like:
  testAssign (__main__.CacheReferenceTest)
  Verify Assign works as expected. ... ok
  testFetchNonGs (__main__.RemoteCacheTest)
  Verify we fetch remote URLs and save the result. ... FAIL
  ...
  ======================================================================
  FAIL: testFetchNonGs (__main__.RemoteCacheTest)
  Verify we fetch remote URLs and save the result.
  ----------------------------------------------------------------------

This makes it a pain to copy & paste the output back to the unittest
invocation to quickly run a few tests.  Lets change it to:
  [__main__] CacheReferenceTest.testAssign
  Verify Assign works as expected. ... ok
  [__main__] RemoteCacheTest.testFetchNonGs
  Verify we fetch remote URLs and save the result. ... FAIL
  ...
  ======================================================================
  FAIL: [__main__] RemoteCacheTest.testFetchNonGs
  Verify we fetch remote URLs and save the result.
  ----------------------------------------------------------------------

Now you can quickly copy & paste things w/out manual fixups:
  $ ./lib/cache_unittest.py RemoteCacheTest.testFetchNonGs

BUG=None
TEST=`./lib/cache_unittest.py -v` output looks good
TEST=`./lib/cache_unittest.py` w/local error added output looks good
