Title: Return 'absent' instead of nil

The current ::virtualenv_version fact returns nil when virtualenv isn't installed. In the module itself however, line 115 of virtualenv.pp requires $::virtualenv_version to be set to something.

The choices are to either allow for null or return something that versioncmp can handle.
