mupdf: explain the OPJ_STATIC comment a bit more in depth

Explain why we restrict OPJ_STATIC ifdef only to Windows. This will
hopefully save some time to debug opj_* undefined symbols when
trying to link libmupdf and accidently omitting the
patches/patch-source_fitz_load-jpx.c hunk (for extra debugging
stories fun, if OPJ_STATIC is defined some opj_* symbols are defined
while others are not defined, making the debugging of that problem
more naughty!).

-- Restrict OPJ_STATIC to Windows (avoid linking errors due to hidden symbols)
+- Restrict OPJ_STATIC to Windows. 
+  This avoid linking errors due to opj_* hidden symbols when linking libmupdf.
 
 - MuPDF does some locking around its allocation calls; it overrides openjpeg's
   allocators to do this locking too. However mupdf tries to manually align things
