Donald Sharp fc3de981be zebra: Allow kernel routes to stick around better on interface state changes 
Currently kernel routes on system bring up would be `auto-accepted`,
then if an interface went down all kernel and system routes would
be re-evaluated.  There exists situations where a kernel route can
exist but the interface itself is not exactly in a state that is
ready to create a connected route yet.  As such when any interface
goes down in the system all kernel/system routes would be re-evaluated
and then since that interfaces connected route is not in the table yet
the route is matching against a default route( or not at all ) and
is being dropped.

Modify the code such that kernel or system routes just look for interface
being in a good state (up or operative) and accept it.
