[libvirt] [PATCH] build: fix incremental autogen.sh when no AUTHORS is present

Commit 71d1256 tried to fix a problem where rebasing an old branch on top of newer libvirt.git resulted in automake failing because of a missing AUTHORS file. However, while the fix worked for an incremental 'make', it did not work for someone that directly reran './autogen.sh'.
