[#492] layer: Don't parameterize basic ACL of created containers

`CreateBucket` handler always creates containers with extended public
ACL, so there is no need to configure it in `NeoFS.CreateContainer`.

Make internal `NeoFS` implementation to create containers with
`eacl-public-read-write` basic ACL if corresponding parameter is unset.
