cli: Use genericGetExpectedHostDetails on s390x

getExpectedHostDetails did not offload any work to
genericGetExpectedHostDetails on s390x. By using that function, much
redundant code can be saved. This also resolves 2 issues with the
previous version:

- The number of CPUs was not calculated.
- vcUtils.SupportsVsocks() still used the Kata v1 signature.

Fixes: #1564
