advapi32: Skip test when registry virtualization can't delete values.

[Vincent Povirk]

See http://source.winehq.org/patches/data/116792 for detailed
description of this failure.

Windows 10's registry virtualization doesn't seem to have trouble with
this test, so I'm marking Windows 8's behavior as broken.
