selftests: hid: add vmtest.sh 



Similar-ish in many points from the script in selftests/bpf, with a few
differences:
- relies on boot2container instead of a plain qemu image (meaning that
  we can take any container in a registry as a base)
- runs in the hid selftest dir, and such uses the test program from there
- the working directory to store the config is in
  tools/selftests/hid/results

Usage: $0 [-i] [-s] [-d <output_dir>] -- [<command>]



<command> is the command you would normally run when you are in

tools/testing/selftests/bpf. e.g:



	$0 -- ./hid_bpf



If no command is specified and a debug shell (-s) is not requested,

"${DEFAULT_COMMAND}" will be run by default.



If you build your kernel using KBUILD_OUTPUT= or O= options, these

can be passed as environment variables to the script:



  O=<kernel_build_path> $0 -- ./hid_bpf



or



  KBUILD_OUTPUT=<kernel_build_path> $0 -- ./hid_bpf



Options:



	-u)		Update the boot2container script to a newer version.

	-d)		Update the output directory (default: ${OUTPUT_DIR})

	-j)		Number of jobs for compilation, similar to -j in make

			(default: ${NUM_COMPILE_JOBS})

	-s)		Instead of powering off the VM, start an interactive

			shell. If <command> is specified, the shell runs after

			the command finishes executing
