[ptxdist] [PATCH] cairo: Try to get rid of gtkdoc dependencies.

[Christian Melki <christian.melki@t2data.com>]

Since the autoconf update, gtk-doc dependencies seems to
have become hard when running autoreconf.
Several other build environments default to building gtk-doc.
I'd prefer not to so this is an effort to disable doc
building entirely.

* Add patch to remove doc building.
* Remove gtk-doc options from rulefile.
