pyproject.toml: add missing dependencies (archlinux#2257)

we were missing 2 dependencies, pyparted and systemd-python(optional), that would lead pip installations to fail sometimes. 

I added them and attributed systemd_python to a new optional dependency group called log since it only seems to be used for system logging:
