Remove hibernate from iot test plan (BugFix)

[hanhsuan]

Description

There is no more hibernate test requirement in the iot project and stress-full test plan is only included in the iot related test plans. Therefore, removing this test from stress-full test plan won't impact other fields.

Should we also remove the actual test plan? https://github.com/canonical/checkbox/blob/main/providers/base/units/stress/test-plan.pxu#L227

From SWE perspective, the hibernate function is most not available on IoT device. So +1 to remove it from the stress test plan.

If any device needs this, it can be added into the project checkbox.
