[kcmkwin/kwinrules] Don't include kdeglobals in rules config

Summary:
There's nothing relevant in kdeglobals and loading it can lead to noise
when deleting groups that override a system default.

We still cascade which will allow kiosk keys to work as well as relevant
system defaults.

Import/Export is unchanged as that already uses SimpleConfig which
includes this flag.

I don't know if it will fix the relevant issue in the bug or just
reduce noise.
