Make Spice file transfer reliable.
This fixes a race condition¹ that sometimes causes Spice file transfers to not be available; I've seen this problem happen in the Journal saved by some test suite runs. Here, we apply the upstream fix² which was included in the spice-vdagent 0.19.0 release. Once we start building Tails based on Buster, this patch will fail to apply, because the changes it brings are already applied, which will hint us that we can remove it.  https://bugzilla.redhat.com/show_bug.cgi?id=1623947  https://lists.freedesktop.org/archives/spice-devel/2018-September/045511.html
