Subject: mkbmdeb: support for lean binary package with only the built modules

 Creates a Debian binary package containing just the binary modules in the
 /lib/modules installation path. This package does not depend on dkms and
 does not require a toolchain to be installed on the target host. Useful
 if you want to have a package to install on hosts identical to the build
 system without installing the full toolchain on them.
