Description of problem

OCI hooks are not working with Kata. Created a rootfs with hook scripts and enabled guest_hook_path = "/usr/share/oci/hooks" in the configuration.toml.
Running the container results in the following error:

time="2020-06-10T11:49:58Z" level=error msg="error waiting for container: context canceled"
The problem got introduced since the following commit a3dec26

Actual result
