deb-pkg: Fix cross-building linux-headers package 

commit f8ce239dfc7ba9add41d9ecdc5e7810738f839fa upstream.

builddeb generates a control file that says the linux-headers package
can only be built for the build system primary architecture.  This
breaks cross-building configurations.  We should use $debarch for this
instead.

Since $debarch is not yet set when generating the control file, set
Architecture: any and use control file variables to fill in the
description.

Fixes: cd8d60a20a ('kbuild: create linux-headers package in deb-pkg')
