Make av_open_input_file() return AVERROR_INVALIDDATA rather than

AVERROR_NOFMT if the format is unknown / cannot be recognized.

It is returned AVERROR_INVALIDDATA, in the sense that the data is
invalid within what the specific libav* binary supports.

That was the last remaining use of AVERROR_NOFMT, which is going to be
dropped at the next libavutil major bump.
