Protect zic's symlink() call with #ifdef HAVE_SYMLINK.

tglsfdc · tglsfdc · commit 534da37927f9 · 2016-03-29T11:06:44.000-04:00
The IANA crew seem to think that symlink() exists everywhere nowadays,
and they may well be right.  But we use #ifdef HAVE_SYMLINK elsewhere
so for consistency we should do it here too.  Noted by Michael Paquier.
