New cfm flower test case is added to the net forwarding selfttests.

Example output:

 # ./tc_flower_cfm.sh p1 p2
 TEST: CFM opcode match test                                         [ OK ]
 TEST: CFM level match test                                          [ OK ]
 TEST: CFM opcode and level match test                               [ OK ]
