[PATCH nft] tests: shell: extend vmap test with updates

[Florian Westphal <fw@strlen.de>]

It won't validate that the update is actually effective,
but it will trigger relevant update logic in kernel.

This means the updated test works even if the kernel doesn't
support updates.

A dedicated test will be added to check timeout updates work
as expected.
