[LTP] [PATCH] controllers/cpuset_hotplug: skip unsupported Microsoft Hyper-V

Hi Krzysztof,

LGTM. How many of tests will need tst_virt_hyperv? Although we don't touch
legacy API, I'd make an exception and add it to both test.sh and tst_test.sh
(ideally with an API extension, i.e. test could use SKIP_VIRT="hyperv", but that
can wait till tests are converted).

Kind regards,
Petr
