udev/udev-ctrl.c:udev_ctrl_new_from_fd() enable SO_PASSCRED
Avoid "sender uid=65534, message ignored" case, where no credentials can be read on the sender side. Seems, the server socket does not enable credential receiving fast enough, and the message from the client (without credential) sometimes is queued before the credential passing was active.
