Hi, we've noticed that some of the emacs tests currently open remote
sockets during a Debian build. Builders and build servers don't always
provide full network access and this can cause false failures during build.

I've attached a patch to disable these tests.

Note that this patch fixes a Debian policy violation (
https://www.debian.org/doc/debian-policy/ch-source.html) which should
qualify this as a "serious" severity bug where:

"For packages in the main archive, required targets must not attempt
network access, except, via the loopback interface, to services on the
build host that have been started by the build."
