environment: "wrong magic" gives the impression of an error

Subject: [PATCH 1/1] environment: "wrong magic" give the impression of an
 error

Introduce a more soft wording when the magic of
the superblock does not match.
Include a hint to the typical reason "(envfs never written?)"

This prevents a "what is wrong?" moment when looking at
the boot log.
