Bug 256800: graphics/cairo: update/revise pkg-plist
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256800



--- Description ---
It seems that cairo no longer provides libdata/pkgconfig/cairo-glx.pc and so
the pkg-plist line for it might need to be removed to permit build and install.
%%OPENGL%%%%X11%%libdata/pkgconfig/cairo-glx.pc

I would also recommend that the plist used match the order of the plist
generated as it makes parsing easier, but that is not essential to
build/install success. 

The very small unified diff which includes all changes is attached.
