Patch: Suppress irrelevant warning when generating a debian package

[Reinhard Karcher <reinhard.karcher@gmx.net>]

Creating a Debian package by compiling the kernel using make bindeb-pkg
without creating debug information creates a warning that no
debug package was created.
This patch excludes the debug package from the control file,
if no debug package is created by this configuration.

The condition to include the debug package is copied from the file
builddeb in the same directory.
