[slurm-users] x11 requires root write access to .Xauthority

in slurm 17.11.5 I just realized that slurmstepd tries to add the X11 
magic cookie into .Xauthority inside root context in order to make x11 
natively work.

The filesystem has to be configured to allow this. I did this 
now, but I am wondering why it could not be done in the user's context the 
same way as the ssh daemon is doing.
