(ddc) Fix deps tracking for the ddc sdk.

The compile_platform template assumes that the output will be in the root-out-dir, and because of that the generated .deps file contains relative paths that only work if the output is in that folder.

It would be nice to fix compile_platform to be more flexible about this, but for now moving the output up fixes the issue that modifications in the sdk were not triggering a rebuild.
