[LTP] [PATCH] lib/tst_virt.c: Add fallback when not using Microsoft Hyper-V hypervisor

[Yang Xu]

If we don't use Microsoft Hyper-V hypervisorm, getrusage04 will report the
following error:
getrusage04    1  TBROK  :  tst_virt.c:175: invalid virt_type flag: 6
getrusage04    2  TBROK  :  tst_virt.c:175: Remaining cases broken

We should add is_hyperv() function when try_systemd_detect_virt returns -1.
But it is a bit complexd according to systemd-detect-virt implementation[1].
Microsoft Hyper-V hypervisor detection has been introduced since long time ago,
most system should support it.
