logind: when we need to execute a sleep operation we don't support, fall back to...

If suspend-then-hibernate, hybrid-sleep or plain hibernation is
supposed to be execute due to a key press/lid switch but is not
supported, automatically fall back to plain suspend (and log about it).

Fixes: #10558
