Implement #2328: unbound.conf: content changed on every puppetrun

This is done by using the include glob capability that is in the
wheezy-backports and newer unbound to include the
/etc/unbound/unbound.conf.d/* config files.

To do this, we need to transition from our /etc/unbound/conf.d directory
structure to use the one that the debian package uses.

This allows us to clean up the rather ugly way we were configuring the
resolver before.
