[Test] Stabilize test_multiple_efs, test_queue_parameter_update, test_proxy, test_build_no_internet, test_cluster_with_gpu_health_checks

Description of changes

Stabilize tests:

• test_multiple_efs: Retry EFS mount assertion for IAM-authorized EFS in test_multiple_efs. The IAM auth can introduce not impactful delays in mounting on reboot.
• test_queue_parameter_update: fix flakiness by asserting the TERMINATE requeue deterministically.
  The TERMINATE branch snapshotted the transient CONFIGURING state via a single-shot after 10 seconds. If the comphute node boots quicker than the update, then the job goes running, not configuring. With this fix we assert on what matters, i.e. the job gets requeued then goes running on the replaced node.
• test_proxy, test_build_no_internet: fixed cfn resource dependency issue that could cause the timeout of ProxyReadyWaitCondition.
• test_cluster_with_gpu_health_checks: reduced the risk of ICEs by ensuring the test consume the reserved capacity.
• test_patching_cluster: prevent false alarm by tolerating the lazily loaded kernel module crc32_generic.
