Drop dbus-python build dependency and tools
dbus-python is long deprecated and unmaintained. I think the only sensible way to do D-Bus from Python is GDBus+pygobject directly.
Drop all uses of dbus-python.
That involves some helper scripts (that probably nobody uses and can just be dropped).
It also involves src/tests/client/test-client.py
and tools/test-networkmanager-service.py
.
Also drop BuildRequires: python3-dbus
from the spec file.
