This reverts commit e5cb1d3.

Reason: bisecting says it breaks dnstap.

Also revert commit 2713454 ("kqueue: use EVFILT_USER for async if available") because otherwise the first commit doesn't revert cleanly, with enough conflicts in src/unix/async.c that I'm not comfortable fixing those up manually.

Fixes: #4584
