Added mail rewrite rule for builder@administrator

[Petter Reinholdtsen <pere@hungry.com>]

The postmasters at uio.no (our hosting site) report that emails from
builder@administrator.skolelinux.no is rejected by alioth.debian.org,
because there is no MX entry and no way to verify where to send return
emails.

I do not know how to best fixed this, but believe I found a workaround
by adding this in /etc/, rewriting the email address of builder to the
commits mailing list:

diff --git a/email-addresses b/email-addresses
index 8e4f2cb..62172ee 100644
--- a/email-addresses
+++ b/email-addresses
@@ -7,3 +7,4 @@
 #
 #user: someone@isp.com
 #otheruser: someoneelse@anotherisp.com
+builder: debian-edu-commits@lists.alioth.debian.org

I hope this make sure we get emails about CD build failures etc.  If
there is a better way to fix this, I would be happy for others to fix it
differently.  The builder user is not supposed to get any emails, so
there is and really should not be no working mail address for it.
