Revert "Add support for writing icc profiles to the jpeg encoder"

This reverts commit 4ef01482025e2e629e35458aa214436d3b4138e8.

Reason for revert: This breaks the android autoroller.

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.
