configs: Exit GPUFS script if DKMS module does not exist
The supported version of ROCm in GPUFS only supports the DKMS build of
the amdgpu driver. However, since a gem5 user can potentially pass in
any Linux kernel as a parameter, it is possible that the DKMS package
for that kernel was not installed on the disk image. This would result
in the simulation appearing to work when in reality it is just spinning
waiting for commands from the driver. This check exits gem5 early in the
simulation and outputs an error on the console to sanity check the
correct driver is being used.
