faultrep/tests: Check for registry virtualization.

If registry virtualization is enabled, AddERExcludedApplicationA
succeeds on Windows 8 even if the user does not really have permission
to write to HKLM\Software. The behind-the-scenes writes to HLKM\Software
are treated like any other writes: They are silently redirected to
HKCU\Software\Classes\VirtualStore\Machine\Software. Since
AddERExcludedApplicationA still fails even with registry virtualization
enabled on Vista, 7, and 10, Windows 8's behavior is clearly broken.

Fixes a testbot failure on 32-bit Windows 8 with a non-elevated
administrator account.
