Bug 1530178 - Fix audiobuffer-copy-channel.html to allow copyFromChannel/copyToChannel wth an offset of n on an array that is n elements long. r=karlt

Browse Source 
This is a no-op, but is allowed per spec:

> An optional offset to copy the data to. If startInChannel is greater than the
> length of the AudioBuffer, an IndexSizeError MUST be thrown.

If the numbers are equals, this shouldn't throw.
