[PATCH v2] iotests: Add more "skip_if_unsupported" statements to the python tests

[Thomas Huth <thuth@redhat.com>]

The python code already contains a possibility to skip tests if the
corresponding driver is not available in the qemu binary - use it
in more spots to avoid that the tests are failing if the driver has
been disabled.

 v2: Thanks to Max' "iotests: Allow skipping test cases" patch (see
     commit 6be012252018249d3a), this patch has been greatly simplified
     by only marking the setUp functions instead of all functions from
     a class.
