nixos/systemd: enable systemd-pstore.service

currently ignored, so we make it part of the sysinit.target manually.

The newly enabled <literal>systemd-pstore.service</literal> now automatically evacuates crashdumps and panic logs from the persistent storage to <literal>/var/lib/systemd/pstore</literal>.
This prevents NVRAM from filling up, which ensures the latest diagnostic data is always stored and alleviates problems with writing new boot configurations.
