Mitigate race caused by flimflam restart in CleanFlimflamDirs()

Mitigate race caused by flimflam restart in CleanFlimflamDirs()

CleanFlimflamDirs() restarts flimflam but does not wait for it to
be fully initialized before returning. This CL mitigates the issue
by restarting Chrome next, giving flimflam ample time to initialize
before the test actually continues. A proper fix will be developed in
crosbug.com/29421.

This is a stop-gap for a race that unbreaks ONC tests. Could you have a quick
look?
