Don't add linux-source to d/control when source: false

With the recent refactor, setting source: false in debian/config/defines
is no longer enough to disable the linux-source-$ver package build, as
dh_listpackages is used to determine what is built.
Do not add linux-source-$ver to d/control if it is disabled.
