Update print/cups-filters to cups-filters-1.13.3

pkgsrc changes:
 - Add --with-apple-raster-filter=rastertopdf to CONFIGURE_ARGS to avoid
   possible PLIST issues with cups<2.2.2 (with cups>=2.2.2 urftopdf is no
   longer built)

Changes:
1.13.3
------
 - libcupsfilters: When auto-generating PPD files added support
   for passing through JPEG input to printers which understand
   JPEG. This is also done in CUPS-generated PPDs (Debian bug
   #851499).
 - libcupsfilters: Added the "output-bin" option support from
   CUPS' PPD generator to our PPD generator (CUPS Issue #4938).
 - cups-browsed: Make support for printers with IPv6 IP address
   work. Both link-local and regular addresses work.
