cmd/run: Unset detach keys when executing commands

Podman sets keys 'ctrl-p' and 'ctrl-q' as the default detach keys. This
behaviour is not desirable in Toolbox. Since Podman v1.8.2[0] it is
possible to have set no detach keys by passing an empty string to the
--detach-keys option.

Thanks to this the 'Ctrl+p' and 'Ctrl-q' combinations are doing what
they should do normally in a terminal.
