output: DBI: fix configuration of DB connection

In `open_db_dbi`, we test whether various config-settings are defined
by comparing their string values to `NULL`.  However, the `u.string`
member of `struct config_entry` is an array, not a pointer, so it is
never `NULL`.  Instead, check whether the string is empty.
