Remove init_path from create

This option was never functional, and was not intended
to be added to the "container create" API, so let's
remove it, because it has been removed in Docker 17.05,
and was broken in versions before that; see

- moby/moby#32355 --init-path does not seem to work
- moby/moby#32470 remove --init-path from client
