Revert "re-land of skslc now automatically turns on derivatives support"

This reverts commit d7d1997643db3b9b5caaaac235c0e2cd0fa23ec2.

This breaks the Chromium roll (it did last time it landed too).
https://codereview.chromium.org/2429853002

Please gate your next attempt on at least one of linux_android_rel_ng, linux_chromium_rel_ng, or mac_chromium_rel_ng.
