Separating command line option parsing from executing hyperkit
makes the code awkward with many parameters passed between functions.
Having everything in one function makes the code simpler.

Some users seem to have Docker for Mac/hyperkit in a non-standard
path. Allow them to specify the path to the hyperkit executable.

- Move HyperKit code into a separate file. It should be compilable
on all supported OSes now.
- Add a (optional) subcommand to "moby run" to select a backend
i.e., "moby run hyperkit [options] [prefix]"
- On macOS the default is "hyperkit" so that:
"moby run [options] [prefix]"
just works
- Add enough command line parsing to make it easy to add new
backends to the run command
