crictl-exec: arg-parsing bug

[vrothberg]

urfave/cli has a bug in how short-options are parsed. The problem is that the parser does not only transform the program's options (e.g., -abc -> -a -b -c) but also undefined ones and even arguments (see a description here containers/podman#714). For Podman, we are currently vendoring a patched version from github.com/vrothberg/cli (see containers/podman#1046). Feel free to vendor that as well if you want the bug fixed. urfave/cli seems to be orphaned at the moment, but once it's back in maintenance we revendor it.

@vrothberg thanks for reporting the bug. Is there any issues or PRs on urfave/cli for tracking the issue?

@feiskyer Sorry, I entirely missed posting the PR for urfave/cli as well: urfave/cli#758
