test: the dead pid comes from a true that both systems have

deadPid spelled /bin/true, which macOS does not have — it is /usr/bin/true
there — so the spawn failed and every reaper test that asks for a dead pid
failed with it: xdg.reapDeadPid, askpass.Listener.start, shellint.install
and AgentRelay.makeDir. Found on PATH instead, which both answer.
