kunit: tool: introduce --qemu_args
Example usage:
$ ./tools/testing/kunit/kunit.py run --arch=x86_64 \
--kconfig_add=CONFIG_SMP=y --qemu_args='-smp 8'
Looking in the test.log, one can see
> smp: Bringing up secondary CPUs ...
> .... node #0, CPUs: #1 #2 #3 #4 #5 #6 #7
> smp: Brought up 1 node, 8 CPUs
This flag would allow people to make tweaks like this without having to
create custom qemu_config files.
For consistency with --kernel_args, we allow users to repeat this
argument, e.g. you can tack on a --qemu_args='-m 2048', or you could
just append it to the first string ('-smp 8 -m 2048').
