enable hibernation on ARM

[Mitchell Dzurick]

[ Impact ]
This is a hardware enablement change to support hibernation on ARM.

Related to https://bugs.launchpad.net/ubuntu/+source/linux-aws/+bug/2060992

[ Test Plan ]
The test plan is the same steps, but tested on both ARM64 and AMD64 to ensure functional enablement and no regressions for amd64.

1. Create an AWS instance
2. Update the hibernation agent
3. Spawn a process
4. Initiate hibernation of the instance
5. Resume the instance
6. Check that the process is still running on the instance

[ Where problems could occur ]
* Regressions in hibernation on amd64 instances due to changes to support arm.

[Mitchell Dzurick (mitchdz)]

I've tested the agent on amd64 instances to ensure no regression when updating. Further results for ARM enablement coming soon.

[Mitchell Dzurick (mitchdz)]

This is the shell script I made to test for amd64 regressions, and the results.

This bug was fixed in the package ec2-hibinit-agent - 1.0.0-0ubuntu17

---------------
ec2-hibinit-agent (1.0.0-0ubuntu17) oracular; urgency=medium

  * d/p/0015-ignore-setting-resume-offset-again-if-dev-snapshot-d.patch: do
    not set the snapshot swap area if /dev/snapshot does not exist. This is
    necessary to enable ARM hibernation. (LP: #2066999)

Successfully tested with the agent on the M6g family. Received 599/600 successful hibernate resumes. The one failure was unrelated to the agent and within reasonable margins.

High level testing steps:
1.) Run M6g Instance.
2.) Connect to the instance and install the PPA (https://launchpad.net/~mitchdz/+archive/ubuntu/ec2-hibinit-agent-arm)
3.) Install kernel with the changes in this bug so that hibernation is enabled. (https://bugs.launchpad.net/ubuntu/+source/linux-aws/+bug/2060992)
4.) Reboot instance and create an AMI from the instance.
5.) Use the created AMI in all remaining steps
6.) Run Instance
7.) Run script on instance to emit timestamped "heartbeat" to dynamoDB table
8.) Hibernate instance
9.) Resume instance
10.) Confirm "heartbeat" is emitted with a new timestamp after resume
11.) Repeat 8-10 once more.
