Subject: [PATCH] fix(xcatserver): keep the server-provided cfgloc before
 rewriting host=

The postscript rewrites host= in the freshly fetched /etc/xcat/cfgloc to point
at MASTER, discarding the database location the credentials came with. That is
the only record of it when the database does not live on the management node.

Keep it as cfgloc.orig; the existing chmod 600 /etc/xcat/cfgloc* covers it.

Recovered from the unmerged lenovobuild branch (10090a9d). The original also
replaced the atomic write with mv-then-sed, which leaves cfgloc truncated if
sed fails, so the write itself is left alone.
