cvsserver: Eclipse compat - browsing 'modules' (heads in our case) works

Eclipse CVS clients have an odd way of perusing the top level of
the repository, by calling update on module "". So reproduce cvs'
odd behaviour in the interest of compatibility.

It makes it much easier to get a checkout when using Eclipse.
