Subject: database: 'sqlite-register' takes a database, not a file name.

* guix/store/database.scm (sqlite-register): Remove #:db-file and add
'db' parameter.  Remove #:schema and 'parameterize'.
(register-path): Wrap 'sqlite-register' call in 'with-database' and in
'parameterize'.
* tests/store-database.scm ("new database")
("register-path with unregistered references"): Adjust accordingly.
