[PATCH v2] iotests: Skip test_stream_parallel in test 030 when doing "make check"

[Thomas Huth <thuth@redhat.com>]

The test_stream_parallel test still occasionally fails in the CI.
Thus let's disable it during "make check" for now so that it does
not cause trouble during merge tests. We can enable it again once
the problem has been resolved.
