yocto: pre-install python3-setuptools package

This package (or python3-distutils, which is a indirect dependency)
is installed in our Yocto kirkstone jobs via an `apt-get install`
call.

Pre-install it to save some time and bandwidth.

This can be removed once we stop supporting kirkstone (around April 2026).
