Update print/cups-filters to 1.11.5

CHANGES IN V1.11.5
 - cups-browsed: Fixed several typos in the documentation (Bug
   #1378).
 - gstoraster, mupdftoraster, pdftops, sys5ippprinter: Use
   execvp() and execvpe() to call programs so that the $PATH
   environment variable gets used to find the programs (Bug
   #1378).
 - build system: Several fixes, especially to make it work when
   cross-compiling or using a build server (Bug #1378).
 - cups-browsed: Silenced a warning.
 - cups-browsed: For remote CUPS queues with a dot in their
   name no local queue got created (Bug #1379).
 - pdftopdf: Do the page logging also for IPP Everywhere
   printers which use the PWG Raster data format as the
   ...toraster filters being the last filter then do not log.
 - gstoraster, pdftoraster: Let filters generate PWG Raster if
   the environment variable FINAL_CONTENT_TYPE is set to
   image/pwg-raster, make sure full-page bitmaps are generated
   in PWG_raster mode, and added mime conversion rules for
   direct PWG Raster output.
 - cups-browsed: Corrected checking of the PDLs of an IPP network
   printer. Now PCL 5c/e printers (not HP inkjets) should get
   recognized correctly.
 - texttopdf: Added missing NULL check to avoid a segfault when
   texttopdf does not find a suitable (monospace TTF) font.
 - foomatic-rip: Replace old manpage macro calls from
   foomatic-filters 3.0.2-20050114.
 - cups-browsed: Allow changing BrowseInterval and
   BrowseTimeout via cups-browsed.conf, as it was formerly with
   CUPS (Debian bug #794655).
 - pdftopdf: Count the actual output pages also if the
   number-up option is not used, to correctly find out whether
   we have an even or odd number of pages, even if the
   page-ranges option is used. This is needed to correctly
   decide whether for duplex printing a blank page has to be
   added (Bug #1377).
