    test_port_security_macspoofing_port: Don't assume DHCP port

    DHCP port is a detail of the reference implementation.
    Non agent based implementations might not provide it.
    Anyway, as the purpose of this test case is to test
    port-security, not DHCP, it's better to avoid assuming
    the existance of DHCP port. Use an ordinary VM instead.
