ccache: update to 4.1

Upstream switched to building with CMake. Adjust accordingly.

Reapplied patch as upstream changed the file format.

Added HOST_BUILD_PARALLEL for faster compilation.

Added cmake tool dependency and removed circular dependencies as a
result.

Adjusted dependent tools to use NOCACHE as they are needed to build
ccache.
