Fix how ExifInterface creates VP8X chunks for WebP files
The current code reads alpha into an int, doesn't shift it back to the
least-significant-bit, and then shifts that value 4 more bits before
writing to the VP8X 'flags' byte. This results in setting the MSB of the
flags byte, which is a reserved bit that must always be zero, resulting
in an invalid file.
VP8X part of WebP spec:
