scripts/sorttable: Have the ORC code use the _r() functions to read

The ORC code reads the section information directly from the file. This
currently works because the default read function is for 64bit little
endian machines. But if for some reason that ever changes, this will
break. Instead of having a surprise breakage, use the _r() functions that
will read the values from the file properly.
