Introduce a seam to ConnectivityManager and TelephonyManager

This change abstracts access to ConnectivityManager and
TelephonyManager behind methods on SystemFacade, moving the code from
Helpers into RealSystemFacade and adding fake implementations to
FakeSystemFacade.  This facilitates new connectivity tests.
