cephfs-shell: don't use pkg_resources since its deprecated

Currently, cephfs-shell prints warnings, hangs and aborts when launched.
This occurs because Python module "pkg_resources" has been deprecated.
We use that module only checking version of other Python modules used in
cephfs-shell. Use "Version" from "packaging.version" instead.
