Add a lastValidated bit and use it when reporting capabilities.

Browse Source 
When we switched the way the status bar determines if a
connection is validated from using INET_CONDITION_ACTION
broadcasts to calling getDefaultNetworkCapabilitiesForUser(),
the statusbar stopped displaying ! when a network stopped having
working Internet connectivity. This is because the validated bit
is never set to false once a network is validated.

Fix this, hopefully temporarily, by introducing a new validated
bit that does go back to being false when a network no longer
has working connectivity, and use that bit in
getDefaultNetworkCapabilitiesForUser().
