Add the case of the ifname being the source of an l2xc to the is_l2() logic1

Browse Source 
This is more strict than VPP itself, which does allow a destination to
be L3 while the source is L2:

DBGvpp# show mode
l3 local0
l3 GigabitEthernet3/0/0
l3 GigabitEthernet3/0/1
l3 HundredGigabitEthernet12/0/0
l3 HundredGigabitEthernet12/0/1

DBGvpp# set interface l2 xconnect GigabitEthernet3/0/0 GigabitEthernet3/0/1

DBGvpp# show mode
l3 local0
l2 xconnect GigabitEthernet3/0/0 GigabitEthernet3/0/1
l3 GigabitEthernet3/0/1
l3 HundredGigabitEthernet12/0/0
l3 HundredGigabitEthernet12/0/1

But it seems undesirable to have Gi3/0/1 be in l3 mode even though it's
the target of a cross connect, so I'm going to leave the behavior
stricter than VPP.
