cdromupgrade not found in artful

During the initial tests of 17.10 (artful) the amd64 and i386 static validation tests failed, due to the fact that the cdromupgrade di file does not exist.

This package has not existed since quantal, however the check was checking on alphabet comparison:

if self.st_release >= 'q':

Now that we have restarted the alphabet this check failed.
