If pvattest perform is executed with options on a non-s390 system the
user gets misleading error messages as the options are not defined.
> pvattest perform -i attestation_request.bin -o attresp.bin
error: unexpected argument '-i' found
This may lead the user to think wrong arguments where chosen, which is
not entirely true as they are valid on s390. The more helpful error
message would be
error: Command only available on s390x
Which is already the case if no arguments are given.
Solve this by allowing non-s390 systems to parse the options:
> pvattest perform -i attestation_request.bin -o attresp.bin
error: Command only available on s390x
While at it ignore some unused code warnings in the exchange format code
that appear on non-s390 systems as not all code is used.
