[libvirt] [PATCH] spec: Automatically apply all patches with git

With this change, any patch declared in libvirt.spec with Patch[0-9]* is automatically applied in %prep. Unlike with the standard %patch[0-9]*, patches are applied with "git am" to avoid some unexpected results. However, as a result of this, all patches must be in the right format for "git am" to be able to apply them; they should ideally be generated from git using "git format-patch".
