textproc/libxslt patch

[Warren Block]

There is a bug in the current release of xsltproc (in textproc/libxslt) 
that prevents it from recognizing the --maxvars option:

https://mail.gnome.org/archives/xslt/2014-October/msg00001.html

https://git.gnome.org/browse/libxslt/commit/xsltproc/xsltproc.c?id=5af7ad745323004984287e48b42712e7305de35c

A port patch file based on that is attached.  It was hand-entered, so I 
might have missed something else.  It does work, though.

Thanks for maintaining the port!
