acquire maintenance lock when running incremental RPZ updates

this addresses a race that could occur during shutdown or when
reconfiguring to remove RPZ zones.

this change should ensure that the rpzs structure and the incremental
updates don't interfere with each other: rpzs->zones entries cannot
be set to NULL while an update quantum is running, and the
task should be destroyed and its queue purged so that no subsequent
quanta will run.
