Revert "Add a cmake build to distcheck to ensure that we distribute all the files necessary to do a cmake build."

We can't know, in autofoo, what arguments are necessary to make 'cmake' actually run successfully on a given system.  We should probably just add a buildbot step to build cmake from the source tarball.

This reverts commit 70a6d204a7f0b4039ee986cd6557cd7242e5ff0c.
