Revert 5cdbd57, causes prolonged delays at shutdown/reboot

Blocking SIGTERM means Finit will wait another two seconds before it
sends SIGKILL, which casues a delayed [WARN] Killing ... before we can
proceed to shutdown/reboot -- not OK.  Don't know what I was smoking
back in 2017, but it must've been good.
