bgpd: Add clear command to force a bestpath recalculation and re-advertisement of a prefix

Add these commands to bgp:

clear ip bgp prefix A.B.C.D/M
clear bgp ipv6 (unicast|multicast) prefix X:X::X:X/M

These two commands forces a bestpath calculation to happen again if
necessary to re-advertise the prefix.
