MaxScale 1.4.1 fails to start on Debian 8 (Jessie)

Opening a new bug as suggested in the comments of MXS-578.

MaxScale 1.4.1 still fails to start on Debian 8 using systemd. This issue I've had in 1.2 and 1.3 also. In 1.3 I was able to bypass it by adding

export _SYSTEMCTL_SKIP_REDIRECT="true"

to /etc/init.d/maxscale

However that is no longer working with MaxScale 1.4.1.

I am able to successfully start MaxScale from the command line manually using:

/usr/bin/maxscale --user=maxscale

When using systemd the service won't start and log files under /var/log/maxscale do not get updated with any new info whatsoever:

1. systemctl start maxscale.service
   Job for maxscale.service failed. See 'systemctl status maxscale.service' and 'journalctl -xn' for details.

1. systemctl status maxscale.service
