bgpd: fix aggregate route best path select
In ebgp+ ibgp deployment aggregate summary-only route
selected path should always be locally originated
summary route.
When aggregate route summary-only config is removed
The selected path is iBGP peer as its lower cost
Upon reconfiguring aggregate route summary-only,
the locally originated is not selected due to
always choosing first path attribute and bailing
out as no change in route update.
