Bump the oci-spec-rs to 0.6.1 to resolve seccomp rule issue

Fix #2022

The detail of the cause of the issue and why 0.6.1 fixes the issue are explained in #2022.

However, the 0.6.1 introduced the time namespace into the runtime spec. For this PR, we set the time namespace to be unsupported. Both libc and nix crate have not provided the support. We should ideally wait for the support to land in either of this crate first before we support it. As a result, there are a number of functions needs to propagate errors now. This is a good add because in the future I imagine we will run into similar situations when new namespaces is introduced.
