stale HibernateLocation EFI variable Currently, if the HibernateLocation EFI variable exists, but we failed to resume from it, the boot carries on without clearing the stale variable. Therefore, the subsequent boots would still be waiting for the device timeout, unless the variable is purged manually. There's no point to keep trying to resume after a successful switch-root, because the hibernation image state would have been invalidated by then. OTOH, we don't want to clear the variable prematurely either, i.e. in initrd, since if the resume device is the same as root one, the boot won't succeed and the user might be able to try resuming again. So, let's introduce a unit that only runs after switch-root and clears the var. Fixes #32021
