bgpd, lib, pbrd, zebra: Pass by ifname

When installing rules pass by the interface name across
zapi.

This is being changed because we have a situation where
if you quickly create/destroy ephermeal interfaces under
linux the upper level protocol may be trying to add
a rule for a interface that does not quite exist
at the moment.  Since ip rules actually want the
interface name ( to handle just this sort of situation )
convert over to passing the interface name and storing
it and using it in zebra.
