description:
make(1): remove anonymous union from struct ListNode

Anonymous structs and unions have been introduced in C11.  The code of
make is supposed to be compatible with C90 though.

The additional members were intended to be used during an interactive
debugging session only and were thus not relevant to running the actual
code.
