stdlib,tests: Fix boot_kvm_fork_run.py

The patch
https://gem5-review.googlesource.com/c/public/gem5/+/51949
changed the way in which kernel arguments were passed to the
'set_kernel_disk_workload' function. The 'kernel_args' parameter
overrides the kernel arguments, not amends them as before. This test
script was not updated to take into account this functionality, and, as
such, the test failed. This patch fixes this.
