Andreas Rheinhardt d5992cc155 avfilter/af_headphone: Don't overrun array 
The headphone filter stores the channel position of the ith HRIR stream
in the ith element of an array of 64 elements; but because there is no
check for duplicate channels, it is easy to write beyond the end of the
array by simply repeating channels.

This commit adds a check for duplicate channels to rule this out.
