selftests: forwarding: vxlan_bridge_1d: Check aging while forwarding

Extend the VXLAN FDB aging test case to verify that FDB entries are aged
out when they only forward traffic and not refreshed by received
traffic.

The test fails before "vxlan: Age out FDB entries based on 'updated'
time":

 # ./vxlan_bridge_1d.sh
 [...]
 TEST: VXLAN: Ageing of learned FDB entry                            [FAIL]
 [...]
 # echo $?
 1

And passes after it:

 # ./vxlan_bridge_1d.sh
 [...]
 TEST: VXLAN: Ageing of learned FDB entry                            [ OK ]
 [...]
 # echo $?
 0
