[bug#35749] SDDM root login issue

[Reza Alizadeh Majd]

There was an issue for root login using SDDM, that was related to hard-coded uid  in sddm-pam-service. 
this patch set's the uid based on `minimum-uid` option in `sddm-configuration`.

Best, 
Reza

Could you send an updated patch that documents the ‘minimum-uid’ field
in doc/guix.texi, under ‘sddm-configuration’?

Apart from that it LGTM.

Thanks for fixing this!

Is it possible to submit further changes to this patch, or I need to submit a new one with whole changes?
