sat-solver: Add workaround for RPM 5 db construction

The first time the database is created on an RPM5 system it works
correctly.  However any subsequent rebuilds cause an empty database to
occur.

The following is from Michael Schroeder <mls@suse.de>:
> rpmdb2solv contains a hack that makes it use the unchanged already
> converted packages. To do this, it needs to get the database id
> for every installed packages by reading the "Name" index. This
> somehow doesn't seem to work with rpm5.
>
> As a workaround you can add a "ref = 0;" line at the top of the
> repo_add_rpmdb() function in ext/repo_rpmdb.c.
