Since this runs at shutdown to write a new seed, we should also keep the bootloader's seed maximally fresh by doing the same. So we follow the same pattern - hash some new random bytes with the old seed to make a new seed. We let this fail without warning, because it's just an opportunistic thing. If the user happens to have set up the random seed with bootctl, and the RNG is initialized, then things should be fine. If not, we create a new seed if systemd-boot is in use. And if not, then we just don't do anything.
