Subject: [PATCH 12/14][user-cr] app_restart(): mnt-pty implies mntns

If the mount_pty is set, mntns must be implied, otherwise the newinstance
mount of devpts will make the ptys in the original pts instance inaccessible.

parse_args() does this correctly, but move the code into app_restart() so
other callers of app_restart() also get this behavior.
