But what is the sense to put a non-working command in dvipdfmx.cfg?
If safety is the issue then it would seem more sensible to enter the
correct entry but to comment it and to ask the user to uncomment it
if they want (x)dvipdfmx to allow to call gs. 

Also obviously previous ghostscript versions don't use the safer
setting, so if more security is wanted texlive should perhaps add
-dSAFER as default so that it breaks at least for everyone ;-) 

BTW: I can reproduce the problem with the miktex if I add to the
line for mgs (the miktex ghostscript) -dSAFER, so its default is
-dNOSAFER.
