gui-apps/wf-recorder: add patch to fix build with ffmpeg 7

With ffmpeg 7 the frame_rate variable has been made private API
which breaks the build for this package. The patch fixes that by
setting the frame_rate variable to a sentinel value because the
frame rate cannot be accessed and is unknown.

Doesn't break building with ffmpeg 6.
