hwsim tests: Add scripts to run in a VM Instead of running on the host, it can be useful to run in a VM, particularly to test kernel rather than userspace changes, so add a few scripts that allow doing so easily. The basic idea is that the VM kernel is the same architecture as the host kernel, so the host's root filesystem can be used (in read-only mode) to run everything. Only a log filesystem is mounted read-write and will get all the test output. The kernel console output is collected to a special 'console' file in the logs directory and kernel crashes are detected.

hwsim tests: Allow setting KERNEL and KVMARGS 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.
