    Fix bash cmd used in scenario trunk tests

    In scenario trunk test test_subport_connectivity there
    is bash command used to check name of base interface on
    spawned vm (e.g. ens3 or eth0), configure vlan interface
    with vlan_id used on trunk port (e.g. ens3.10),
    make this vlan device up and run dhclient on this interface
    if it's not running yet.

    This command was broken and that cause failure of this test.
