PATCH 1/1 build/runqueue: Add noextra stamp file parameter to fix multiconfig builds

We can't execute the same task for the same package_arch multiple times as the current setup has conflicting directories. Since these would usually have the same stamp/hash, we want to execute in sequence rather than in parallel, so for the purposes of task execution, don't consider the "extra-info" on the stamp files. We need to add a parameter to the stamp function to achieve this.

This avoids multiple update-rc.d populate_sysroot tasks executing in parallel and breaking multiconfig builds.
