[Qemu-block] [PATCH v4 3/7] iotests: Use case_skip() in skip_if_unsupported()

[Max Reitz]

skip_if_unsupported() should use the stronger variant case_skip(),
because this allows it to be used even with setUp() (in a meaningful
way).

In the process, make it explicit what we expect the first argument of
the func_wrapper to be (namely something derived of QMPTestCase).
