Fix selecting SQLite database files with sql-mode (Bug#23566)

* lisp/progmodes/sql.el (sql-sqlite-login-params): Allow any name as
SQLite database file name, by default.
(sql-get-login-ext): Fixed read-file-name arguments to provide
path completion even if a database name pattern is customized and to
allow creation of new SQLite database files.
