Log Message:
diff3(1): Just use waitpid(2), no need for kevent(2).

Sidesteps

PR kern/60358: kevent EVFILT_PROC races with process exit

in order to fix

PR bin/60357: diff3(1): tests are failing since BSD diff import

The FreeBSD version used kevent(2) until February of this year:
https://cgit.freebsd.org/src/commit/?id=404753664a5e145d98f1749d1c7bc046c8aa32c3
So this reduces diff from FreeBSD somewhat, except FreeBSD uses
capsicum and process fds rather than pids.
