Reduced logging and better log format for PyAuto WaitUntil().

Reduced logging and better log format for PyAuto WaitUntil().

Since most calls to WaitUntil use lambdas, you commonly see a lot of:
DEBUG    WaitUntil(<function <lambda> at 0x79b984c4>) still waiting. Expecting None. Last returned False.
With this change it is instead:
DEBUG    WaitUntil(pyauto.py:281 self.WaitUntil(lambda: _AreOrigPidsDead(orig_pids))) still waiting. Expecting True. Last returned False.

Also reduce the frequency to once every 5 seconds.


BUG=None.
TEST=Run any PyAuto test that uses WaitUntil().
