FFMPEG_CONFIGURATION and FFMPEG_VERSION were concatenated into av_log
format strings, so any % in them was interpreted as a conversion
specifier and consumed unrelated varargs, causing undefined behavior
ranging from garbled output to a segfault on `ffmpeg -version`. Pass
both as %s arguments instead.
Fixes issue #23662.
The FFMPEG_CONFIGURATION fix is based on a patch by FinnRG; the
FFMPEG_VERSION case is fixed here as well.
