Fix hibernation

The resumeDevice and kernel `resume` parameter were being used wrong.

Only `boot.resumeDevice` is necessary, and it should point at the _block
device_ that holds the swapfile. If you are running on encrypted
volumes, this means you will need to use the name of the *decrypted
block device* on which the swapfile sits.
