criu --help: fix --cgroups-props-file

* fix a typo (descrition -> description)
* add a comma before "but"
* remove a period at the end of the sentence

Was:
  --cgroup-props-file FILE
                        same as --cgroup-props but taking descrition
                        from the path specified.

Now:
  --cgroup-props-file FILE
                        same as --cgroup-props, but taking description
                        from the path specified
