[master] Disabled forceUDPSendError unit test for Solaris

The goal of these tests is to exercise error handling of a failed NCR send
in Kea4/Kea6.  Because the test is for a UDP sender is there is no simple way
to make the send fail.  The only way found so far is to attmpt to send it to
0.0.0.0/port 0.  This fails everywhere except Solaris 11. For now the tests
have been disabled for Solaris 11
