[libvirt] [PATCH] Change virCgroupGetAppRoot stub on non-Linux to avoid unused param warning

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

Fully stub out the virCgroupGetAppRoot method as done with other
methods in the file, rather than just the body. This lets us
annotate the unused parameter to avoid a warning

Pushed as a Win32 build breaker fix
