A self-hosting packagegroup needs to ship Python 3 for bitbake, not Python 2.
Remove python-compiler as it was a standard module in Py2 and removed in Py3.
Remove python-misc as it is pulled in via python3-modules.
Remove python-rpm as it is only required by Smart, and if smart is installed
then python-rpm will be too.
