Hibernation Test case fixes (#3532)

* Hibernation: Add CBLMariner to Unsupported Distros

* Hibernation: Check last reboot instead of uptime.

Uptime -s has two issues.
1. It rounds up the time, hence the boot time may change by 1-2 seconds when querying after hibernation
2. The tool is not consistent across distro's

* Hibernation RHEL: Reboot after hibernation-setup-install

In RHEL, Hibernate-resume fails if it is done immediately
after executing hibernation-setup-tool.
The root cause is yet to be found, adding a sleep(100) also works
but since we do not have an explanation for "why 100 seconds", use
reboot.

* Hibernation: Update Supported Distros
