David ec708dbde2 fix(libkernel): take the watched kqueue's count and activations in one snapshot ...

A cleared kqueue watch read the watched queue's triggered count and its
activation counter under two separate locks, so an activation between the
reads was marked seen without making the watch active, and the wakeup was
lost. SnapshotTriggered now returns both under one lock. Every poll of an
active watch also rechecks the count, as kqueue_scan reruns filt_kqueue:
it drops when the watched queue empties and reports the current count.
EV_ADD and EV_ENABLE of an existing watch re-arm it. A separate
guest_kqueue_cleared_race test triggers the watched queue from another
thread while the watching queue waits.
