ifupdownaddons: iproute2: fix 'ifquery -c' fail for 'bridge-pvid' on bridge ports

Ticket: CM-11624
Reviewed By: roopa, julien
Testing Done: using configuration mentioned in the bug

This patch fixes 'ifquery -c' failure for 'bridge-pvid' on
all bridge ports.

The following format of '/sbin/bridge -c vlan show' output was not handled properly
by iproute2

port  vlan ids
swp1   600
       700-710
       711 PVID Egress Untagged
       712-900

iproute2 was parsing the '/sbin/bridge -c vlan show' output with the assumption that
pvid line '711 PVID Egress Untagged' appears before all the vland ids.

Something like this:
port  vlan ids
swp1   711 PVID Egress Untagged
       600
       700-710
       712-900
