Current defaults on interface exclusion lists a wrong interface for RHV/oVirt's vdsmdummy interface

Version-Release number of selected component (if applicable):
foreman-1.22.0.32-1.el7sat.noarch

How reproducible:
Always

Steps to Reproduce:

Actual results:
Defaults to "_vdsmdummy_", does not list "br-int" of OVS

Current interface output of a RHV-Linux hypervisor with OVS enabled:

1. ip l |egrep "vdsmdummy|br-int"
   7: br-int: <BROADCAST,MULTICAST> mtu 1442 qdisc noop state DOWN mode DEFAULT group default qlen 1000
   40: ;vdsmdummy;: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
