acceptance: do not try to rm /var/run/ceph

Some acceptance tests try to remove /var/run/ceph, which contains some
sockets.

Puppet does not seem able to delete sockets:
"Failed to generate additional resources using 'eval_generate': Cannot
manage files of type socket"

See https://tickets.puppetlabs.com/browse/PUP-4045

We should not try to delete sockets in puppet-ceph, cleanup is just
removing packages, repos and data directories.
