tst_QUdpSocket: add some tests for link-local IPv6 multicasting

Browse Source 
Unlike higher scopes (like scope 4, admin-local, which the last commit
used), scopes 1 and 2 require a scope in order to bind, even if some
operating systems are lenient. So test that we are able to bind to them
and do bind properly.
