libvirtd service starts every rebuild

[llakala]

Issue description

As described in the title, the libvirtd service is started on every rebuild. Ideally, it would only starts on relevant changes to its config. My rebuild output after making no external changes:

~ ❯ sudo nixos-rebuild switch
building the system configuration...
activating the configuration...
setting up /etc...
reloading user units for emanresu...
restarting sysinit-reactivation.target
the following new units were started: libvirtd.service

Steps to reproduce

Set virtualisation.libvirtd.enable = true;
