[rancid] excluding output from cisco routers and switches

[allonon]

With further digging, I found out that part of this code to remove the 
fluctuating wattage is in the nxos.pm module but the code is based on a 
different output than what I am getting from our Nexus hardware.

So now to figure out how the existing code is actually stripping the 
wattage and adjust it for my output
