Under slow network conditions (e.g., simulated 2 Mbps ingress bandwidth
limits in CI), restoring a container from a checkpoint can fail if it
requires pulling the base image again.

During restore, crictl create is called. In test_from_oci, it used a
10-second timeout (crictl -t 10s create). Over a 2 Mbps connection,
pulling the 2.8MB Alpine layer takes ~12-13 seconds, causing the
operation to exceed the timeout and fail with context canceled.

Increase the timeouts in both test_from_archive and test_from_oci to
30 seconds. This ensures the base image pull can complete successfully
even in constrained CI environments.

Tested:
Ran the CRI integration tests on a GCE VM under a simulated 2 Mbps
ingress bandwidth limit using traffic control (tc). Verified that
both test_from_archive and test_from_oci passed successfully and
container restore completed without timeout.
