Commit id '887dd362' added support for a netfs pool format type 'cifs' and 'gluster' in order to add rng support for Samba and glusterfs netfs pools. Originally, the CIFS type support was added as part of commit id '61fb6979'. Eventually commit id 'b325be12' fixed the gluster rng definition to match expectations. As it turns out the CIFS rng needed a similar change since the directory path is not an absDirPath, rather just a dirPath will be required.

https://bugzilla.redhat.com/show_bug.cgi?id=1186969 When generating the path to the dir for a CIFS/Samba driver, the code would generate a source path for the mount using "%s:%s" while the mount.cifs expects to see "//%s/%s". So check for the cifsfs and format the source path appropriately. Additionally, since there is no means to authenticate, the mount needs a "-o guest" on the command line in order to anonymously mount the Samba directory.
