hibernate-resume-config: log louder on invalid kernel version/os-release id

We do make use of the os-release ids to determine whether to initial resume
if they're present, hence log at warning level if invalid. While at it,
raise the level for the kernel version too, which is generally interesting
to the user if something goes wrong.
