After doing a full build, it seems there was still stuff not being
ignored correctly. This change should take care of that.
So after debian/rules orig, debian/rules debian/control-real and doing a
package build, there are no files in debian/ showing up as untracked
content. When cleaning out everything using git clean -dfx, there are no
files in debian/ which are listed when doing git status --ignored.
