[libvirt] [PATCH 1/2] virnetdev: move virNetDevSysfsFile() upwards

[Lubomir Rintel]

...and provide a bogus implementation for non-Linux. No functional change.
We'd like to use it from within virNetDevSetNamespace() to determine if we need
to move a 802.11 PHY to a namespace when moving the interface.
