Remove our forcing of analyzeduration and probesize as they seem to

cause weird problems when scanning some files.  The unit test case
added here is a case in point: before this patch one
stream reported an incorrect channel count and sample rate.

It's a bit worrying as these parameters have been in DoM for many years,
but perhaps they have become unnecessary / harmful with changes to FFmpeg.
