neighbour: Floor neigh_periodic_work() interval at 1s.
neigh_periodic_work() reschedules tbl->gc_work with a delay of
BASE_REACHABLE_TIME >> 1.
neigh_table is now per-netns, and a user could hog CPU by setting
BASE_REACHABLE_TIME to a small value.
Unlike INTERVAL_PROBE_TIME_MS, BASE_REACHABLE_TIME is also used to
compute reachable_time for NUD_REACHABLE entries.
Let's floor only the GC interval at 1 second.
