sd-id128: return -ENOMEDIUM on null id
We currently return -ENOMEDIUM when /etc/machine-id is empty, and -EINVAL when it is all zeros. But -EINVAL is also used for invalid args. The distinction between empty and all-zero is not very important, let's use the same return code. Also document -ENOENT and -ENOMEDIUM since they can be a bit surprising.
