When using qemuProcessAttach to attach a qemu process, the DAC label is not filled correctly. Introduce a new function to get the uid:gid from the system and fill the label. This fixes the daemon crash when 'virsh screenshot' is called: https://bugzilla.redhat.com/show_bug.cgi?id=1161831 It also fixes qemu-attach after the prerequisite of this patch (commit f8c1fb3) was pushed out of order.

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
