[PATCH nfs-utils] start-statd: clean up output when systemd is not installed

[Mike Frysinger <vapier@gentoo.org>]

If you don't have systemd, then this script dumps:
/usr/sbin/start-statd: line 8: systemctl: command not found

This isn't terribly useful since we ultimately fall back to running
the daemon ourselves, so probe for systemd's existence before we try
to use it.
