bitbake: 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.
