PM / Hibernate: Restore old swap signature to avoid user space breakage

Commit 3624eb0 (PM / Hibernate: Modify signature used to mark swap)
attempted to modify hibernate signature used to mark swap partitions
containing hibernation images, so that old kernels don't try to
handle compressed images.  However, this change broke resume from
hibernation on Fedora 14 that apparently doesn't pass the resume=
argument to the kernel and tries to trigger resume from early user
space.  This doesn't work, because the signature is now different,
so the old signature has to be restored to avoid the problem.
