[PATCH] hwsim tests: allow setting KERNEL and KVMARGS

[Johannes Berg]

From: Johannes Berg <johannes.berg at intel.com>

Rather than just having KERNELDIR, allow setting KERNEL directly.
Also remove the -s option that prevents running multiple machines
at the same time, but add a KVMARGS= variable that can be used to
restore that if needed.
