bgpd: Actually find the sequence number for `bgp extcommunity-list...`
The code in the bgp extcommunity-list function was using
argv_find to get the correct idx. The problem was that
we had already done argv_finds before and idx was non-zero
thus having us always set the seq pointer to what was last
looked up. This causes us to pass in a value to the
underlying function and it would just wisely ignore it
causing a seq number of 0.
We would then write this seq number of 0 and then immediately
reject it on read in again. BOO!
Actually handle argv_find the way it was meant to be.

zebra: Fix zebra crashed in building FPM netlink message when bgp sends aggregation routes to zebra.
Issue:
When BGP sends aggregation routes to zebra, the next hop is black hole.
Then Zebra will try to build the netlink FPM message, but there is no
next hop as it is a black hole route. Then the netlink_route_info_fill
function returns 0. In the result, zebra will crashed in
"assert(data_len)" of zfpm_build_route_updates.
This issue also happen when I create a static black hole route via
staticd.
Fix:
As the netlink message of the blackhole route is legal, it should return
success.

tests: Allow a useful amount of time for bgp to converge
The bgp_as_wide_bgp_identifier test can time out after
