nixos/systemd-nspawn: use config.systemd.package

When using a modified systemd-package (e.g. to test a patch), it's
recommended to use the `systemd.package`-option to avoid rebuilding all packages
that somehow depend on systemd.

With this change, the modified package is also used by `systemd-nspawn@`
units.
