[libvirt] [PATCH libvirt] Reject any non-option command line arguments

[Daniel P. Berrange]

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

Due to a bug in editing /etc/sysconfig/libvirtd, VDSM was causing
libvirt processes to run with the following command line args

   /usr/sbin/libvirtd --listen '#' 'by vdsm'

While it correctly rejects any invalid option flags, libvirtd
was not rejecting any non-option command line arguments

* daemon/libvirtd.c: Reject non-option argv
