gpu-compute,configs: Make sim exits conditional

Browse Source 
The unconditional exit event when a kernel completes that was added in
c644eae2dd is causing scripts that do not
ignore unknown exit events to end simulation prematurely. One such
script is the apu_se.py script used in SE mode GPU simulation. Make this
exit conditional to the parameter being set to a valid value to avoid
this problem.
