sleep: Add debug feature to bypass hibernation memory checks. (#3064)
This new feature bypasses checking if a swap partition is mounted
or if there is enough swap space available for hibernation to
succeed.
This can be useful when a system with a Solid State Disk (SSD)
has no normal swap partition or file configured, and a custom
systemd unit is used to mount a swap file just before hibernating
and unmount it just after resuming.
