Add a tiny bit more verbosity to validate.py

validate.py did not give any progress ahead of which books are going to
get build which is a bit annoying if you run it locally.

With my patch you see:
$ tools/validate.py

Following files will be validated:
>>> doc/src/docbkx/openstack-network-connectivity-admin/app_demo_routers_with_private_networks.xml

Queuing the following books for building:
  openstack-network-connectivity-admin
Building all books now...
>>> Build of book openstack-network-connectivity-admin succeeded.
