[PATCH] contrib: Add missing includes to pipewiregrab patch.

[Maxim Cournoyer]

Otherwise, GCC 13 would complain about implicit declaration of
functions, e.g.:

   libavfilter/vsrc_pipewiregrab.c:1352:12: error: implicit
   declaration of function ‘ff_set_common_formats_from_list’
   [-Werror=implicit-function-declaration]
    1352 |     return ff_set_common_formats_from_list(ctx, pix_fmts);
         |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

* contrib/src/ffmpeg/pipewiregrab-source-filter.patch: Include
libavfilter/formats.h and libavfilter/video.h.
