[libvirt] [PATCH 2/6] Workaround issue with clang and inline functions with static vars

[Daniel P. Berrange]

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

Clang does not like it when you pass a static variable to an
inline function

 vircgroupmock.c:462:22: error: static variable 'fakesysfsdir' is
  used in an inline function with external linkage [-Werror,-Wstatic-in-inline]

Just make the var non-static to avoid this
