Document_ftp: *only* serve databases that have the module installed.

The document_ftp is not really a database-specific server, but a
server-wide implementation. So, it could normally serve all the databases
of the server, once one of them has it installed. Limit that and instead
only serve the dbs that have the module marked as installed.
