Revert "Add support for writing icc profiles to the jpeg encoder"
This reverts commit e3b95ce468c73af8247ba9582a7b84548b19f06a.
Reason for revert: This is breaking the Android auto roller.
Original change's description:
> Add support for writing icc profiles to the jpeg encoder
>
> Also, share the impl for skjpeg_error_mgr between the
> jpeg decoder and encoder. They are already identical
> anyway.
