Add support for bridge over bond/team/vlan.

Browse Source 
Kdump module doesn't check if bridge is stack on other complex interface
and setup proper dracut cmdline. That makes dracut fail to setup a working
network environment in 2nd kernel.

This patch adds the ability to setup proper dracut cmdline for bridge over
bond/team/vlan. Although in this timeframe, drauct only supports bridge over
bond among these three complex network, it's worth fixing the other two types
(bridge over team/vlan) along with. It would be much easier for us once
the dracut part is done.
