Relax hibernation check by both checking for lower case "hibr" and
upper case "HIBR" hibernation file magic and by not checking the
first four kilobytes of the hibernation file against being zero.

This relaxed checking followed the equivalent relaxation in NTFS-3g
in commit 64f9f0dc1a7ed9766dac431b1f300536c394ec91.
