[libvirt] [PATCH v2 05/23] qemu: add socket datagram capability

From: Marc-André Lureau <marcandre.lureau(a)redhat.com&gt; Datagram socket is available since qemu 4.0, commit fdec16e3c2a614e2861f3086b05d444b5d8c3406 ("net/socket: learn to talk with a unix dgram socket"). Required for slirp-helper communication.
