handle ifup on RH distros by iterating over 'ifup devname'

Fix the ifup so that if a list of devices is provided then each interface is
brought up individually instead of using the '--all' which isn't on rhel. 

The default debian behavior will be to use this still though as it overrides
the new bring up interfaces function for this case.
