    host-ctr: bump dependencies
    
    - Bumps host-ctr's dependencies.
    - Bumps containerd dependency from v1.3.7
    to v1.4.3 to match Bottlerocket's packaged containerd version.
    - Replaces `withAllDevicesAllowed` with upstream's
    `oci.WithAllDevicesAllowed`
    - go mod tidy
    - Drops patch 0001-Use-spec-s-mountLabel-when-mounting-the-rootfs.patch
    since it's in containerd v1.4.3

Testing done:

Build image and AMI successfully, launched instance.
Saw both admin and control host-containers come up fine.

I was able to repeat the testing done in #1037

No permission errors when trying to access the partitions.
