Daniel P. Berrange a93a3b975c avoid using deprecated udev logging functions
In systemd >= 218, the udev_set_log_fn method has been marked
deprecated and turned into a no-op. Nothing in the udev client
library will print to stderr by default anymore, so we can
just stop installing a logging hook for new enough udev.
