[OSSTEST PATCH 56/82] subst_netboot_template: Do not use all of %r

[Ian Jackson]

From: Ian Jackson <ian.jack...@eu.citrix.com>

Instead of copying all of %r into %v, have the template substitutor
fall back to %r from %v.

This is going to be important when we have host-reuse-related access
control to %r.
