Due to a systemd bug [1], building systemd-sysupdate does not require that systemd-pull is built as well. However, systemd-sysupdate has a run-time dependency on systemd-pull. Therefore, override the systemd derivation so that systemd-pull is built. Confusingly, this requires enabling systemd-importd. If systemd-pull or systemd-sysupdate is not built, the resulting image will be broken and users will not be able to recover without either a reinstall or reverting to the previous version. Therefore, add a check to ensure that both are in fact built. Use 'cat' rather than just 'stat' to catch broken symlinks and the like.
