Simply get rid of an intermediate buffer of size width x height, by
using the fact that stride == width in this case.

Removed a call to WebPParseHeaders() inside VP8GetHeaders(). This was not needed
anyway, as all call flows already call WebPParseHeaders() before calling
VP8GetHeaders().
This avoids duplicate calls to WebPParseHeaders().
