Subject: [PATCH] fix(provtest): give makedns a name it can resolve for this
 machine

makedns looks up the server of each zone it writes and qualifies it with
site.domain. On a cluster whose networks name their server as
<xcatmaster> that name is this machine's own, inside the fixture's
domain, which nothing resolves -- so makedns failed and every wire case
died in setup. It passed where the other networks name no server and the
lookup fell back to site.nameservers, an address.

Add the qualified name to /etc/hosts, which teardown already restores.
