[libvirt] [PATCH 4/7] Ensure GET_VLAN_VID_CMD is always defined

[Daniel P. Berrange]

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

The RHEL4 vintage header files do not define GET_VLAN_VID_CMD.
Conditionally define it in our source, since the kernel can
raise a runtime error if it isn't supported
