ppa builds are built without cgo

[Andrew Wilkins]

The PPA builds (at least in the dev PPA) are built with CGO_ENABLED=0.

This is what caused bug #1225825. net.LookupIP fails when using the non-cgo version, but not the cgo version. I can (and will) change the code to check if an IP is specified first, but I'm not sure if we should be building without cgo. Since we have different tools for different series (thus we can make guarantees about libc), is there any benefit?

I know we want to avoid using CGO for stuff like Windows. But my
personal recommendation would be "it is fine to use if we have it, but
we shouldn't require it".

That said, if we aren't going to use it everywhere, and it has
*functional* differences, then maybe we shouldn't use it anywhere. So
that we discover bugs like this earlier, rather than as some obscure
difference on some different platform.

The dev PPA was depending on my personal golang backports PPA which is out of date and buggy with reference to CGO.

I've amended the dependencies here:

CGO should be OK once you rebuild.
