Update spec tests

This commit updates the spec tests so that they should work.

- the ssh module that they depend on had introduced a dependency on
  the operatingsystem fact
- tests had not been updated to reflect using xinetd and not the service
to run the rsync daemon
- update travis-ci to include the xinetd module
