pbrd: add advisory flag PBR_ACTION_DROP
PBR configuration may specify "set nexthop blackhole" which,
for linux dataplanes, is implemented as a table with a blackhole
route.
Other dataplanes might implement this action as an explicit
packet-filtering "drop" action instead of a route. This new flag
PBR_ACTION_DROP is now set when a rule has "set nexthop blackhole"
as an aid to other dataplanes.
