The seen/file-names script relies on f$info$filename to be populated. For HTTP and other network protocols, however, this field is only populated during file_over_new_connection() that's running after file_new(). Use the file_new() event only for files without connections and file_over_new_connection() implies that f$conns is populated, anyway. Special case SMB to avoid finding files twice, because there's a custom implementation in seen/smb-filenames.zeek. Fixes #2647
