Bug description

The greeter syncer requires pkexec with the setuid bit enabled. However, I have disabled the pkexec wrapper on my system because I use run0 as my privilege escalator. run0 utilizes polkit for authentication without relying on setuid.

Steps to reproduce

1. Set up the Noctalia greeter.
2. Disable the pkexec wrapper (e.g., set security.wrappers.pkexec.enable = false on NixOS).
3. Attempt to sync the greeter from Noctalia settings.

Expected behavior

The greeter syncs successfully. (Verified that it works as expected when the pkexec setuid wrapper is enabled on my system).

Actual behavior

The sync process fails.
