Don't use deprecated calls with modern SVG library

Removes the following warnings:
• stock_pixmap.c:545:9: warning: ‘rsvg_handle_get_dimensions’ is
  deprecated: Use 'rsvg_handle_get_intrinsic_size_in_pixels' instead
• stock_pixmap.c:554:9: warning: ‘rsvg_handle_render_cairo’ is deprecated:
  Use 'rsvg_handle_render_document' instead
• stock_pixmap.c:675:17: warning: ‘rsvg_handle_get_dimensions’ is
  deprecated: Use 'rsvg_handle_get_intrinsic_size_in_pixels' instead
