The cleanup script used for router, network, server, and flavor does not
account for the first column being the resource ID. Matching via
^[sc]_rally will always result in an empty return. This fix now correctly
matches the the name of the second column. This also fixes an issue where
rally creates flavor as "private", adding --all so it cleans up the
private flavors as well.
