Update print/cups-filters to cups-filters-1.12.0

Changes:
CHANGES IN V1.12.0
 - cups-browsed: Added new "CreateRemoteCUPSPrinterQueues"
   directive to cups-browsed.conf, which allows to decide
   whether to auto-create local print queues for shared CUPS
   queues on remote machines. This way one can also set up
   servers which only create queues for IPP network printers.
 - driverless: Added new /usr/lib/cups/driver/driverless
   utility to make CUPS auto-generate PPD files for printers
   designed for driverless use (IPP Everywhere, Apple Raster)
   when they are set up with a printer setup tool. This gives
   transparency to set up these printers with legacy printer
   setup tools. This utility is also linked to /ustr/bin to
   manually generate PPDs via command line.
 - libcupsfilters, cups-browsed: Moved the PPD generator for
   IPP network printers from cups-browsed to libcupsfilters, so
   that it can also be used by other utilities.
 - cups-browsed: When auto-generating a PPD set the cost values
   in the filter lines to give the highest priority to PDF,
   then PWG Raster, Apple Raster, PCL-XL, PostScript, PCL 5c/e.
 - cups-browsed: Synced the PPD generator with the one of CUPS,
   giving the best possible support for IPP Everywhere and
   AirPrint printers. Especially support for more media types
   and for finishing units got added. Also support for more
   different ways to represent the printer capabilities via
   IPP attributes got added.
 - cups-browsed: Added support for auto setup of IPP printers
   understanding the Apple Raster input data format (.urf, on
   AirPrint printers), only if CUPS 2.2.2 is used, which can
   generate this format via its rastertopwg filter.
 - cups-browsed: Added new "NewIPPPrinterQueuesShared"
   directive to cups-browsed.conf, which allows to decide
   whether the auto-created local print queue for a newly
   discovered IPP network printer will be shared or not. For
   printers discovered earlier, cups-browsed remembers the
   previous setting.
 - cups-browsed: If a user changes the printer-is-shared bit of
   an auto-created print queue for an IPP network printer (not
   for a remote CUPS queue), record this fact and recover the
   change when creating this queue in the next session.
 - cups-browsed: For automatic creation of print queues for IPP
   network printers also allow only creating queues for IPP
   Everywhere printers, only for Apple Raster printers, or for
   both printer types designed for driverless printing and not
   only for all suitable printers, configurable via the
   CreateIPPPrinterQueues directive in cups-browsed.conf.
