systemd/avoid-random-hangs-on-timeouts-due-lost-cwd.patch

Found this during debugging an other problem.  The issue was that
after ``sudo -i'' and a ``cd /usr/lib/systemd/system/'' followed
later by a shutdown may fail with (journalctl -b -1):

 systemd-exit.service: Failed at step CHDIR spawning: /usr/bin/kill

which then caused the subsequent fault that umounting the users
home directories done by automount are busy.
