Use $file rather than $module in llds_out_data.m

When calling unexpected($module, $pred, Error) the $pred variable already
contains the module name, so including $module is redundant.  It's more
useful to include $file.  This change modifies llds_out_data.m to use $file
rather than $module all the calls to unexpected/3.
