[Pm-utils] [Patch] add userspace suspend signature to pm-reset-swap

[Stefan Seyfried]

Hi,

This adds the userspace suspend signature to pm-reset-swap.c, it also
fixes the "always reset the signature, regardless if there is a suspend
image" problem, that could easily corrupt a filesystem if the wrong
partition is given.
The printf for "no signature found" is not really necessary, but i found
it useful :-)
