Trust signalfd on illumos, again.
Commit 3ab4fc5d avoided choosing signalfd by default on illumos, because it triggered kernel panics. That was fixed, so we can remove a kludge from our code. Users/packagers can still override the default choice at compile time if desired, and we'll leave the back-branches unchanged so they keep choosing self-pipe by default, but we'll default to signalfd (like we do for Linux) in 17. Fixed kernels should be everywhere by the time 17 ships. The illumos issues were: * https://www.illumos.org/issues/13700 * https://www.illumos.org/issues/14892 Discussion: https://postgr.es/m/CA+hUKG+NK-K_G_i1H3OpDTwYPEsiwQi_jw58PGcW2H+-N2eVCA@mail.gmail.com
