Fix playing of 8-bit sample files via webaudio.
The bias for 8-bit samples was incorrectly applied.
To hear the bug, go to the url: http://www.corp.google.com/~rtoy/audio/latency.html
Press space. This should play 2 sec of an 8-bit wave file. You will hear just a click instead of a man (on one channel) and a woman (on the other channel) speaking different sentences.
