The function SVGSurfaceSetDocumentUnit doesn't work with Cairo older than version 1.16, because it didn't have the function cairo_svg_surface_set_document_unit. This caused compiling of go-cairo to fail.
This update adds a do-nothing implementation of cairo_svg_surface_set_document_unit if the detected version of Cairo is older than 1.16.
