Fixes to get the chrome frame network tests up and running on the chrome frame builder.

Fixes as below:-
1. Instantiate the SystemMonitor object as it is needed to instantiate the profile.
2. Adds the single-process command line to the chrome_frame_net_tests executable to ensure
   that the webkit thread gets initialized correctly.
3. Register additional prefs in the profile to get around some DCHECKS which fire in debug
   mode
