d/control: remove linux-libc-dev binary package

This avoids conflicts with the one from Debian.

I at least value safe, quick kernel updates more than reasoning about this for a long time. And if it's necessary, let's do this.

Closes: #492 (closed)

let's not sqash this anywhere so that we can easily build it any time.
