Only allow forwarding of Intents that MATCH_DEFAULT_ONLY 

When IntentForwarderActivity is launched by PMS in response to a web
URI, the only way it can pass domain verification is by declaring
the DEFAULT category. Either explicitly or implicitly through
MATCH_DEFAULT_ONLY added by startActivity.

This makes the PackageManager API that checks if the Intent forwarding
is allowed mirror the web Intent validation so that only DEFAULT
marked Intents can be forwarded.
