bgpd: ensure that bgp_generate_updgrp_packets shares nicely

The bgp_generate_updgrp_packet function will attempt to write
up to `write quanta 64` packets at one time.  This is extremely
expensive at scale and is causing CPU_HOGS as well as STARVATION
messages.  Check to see if we should yield the CPU to allow
something else in BGP to continue working.
