kbuild: slim down package for building external modules

Exclude directories and files unnecessary for building external modules: - include/config/ (except include/config/{auto.conf,kernel.release}) - scripts/atomic/ - scripts/dtc/ - scripts/kconfig/ - scripts/mod/mk_elfconfig - scripts/package/ - scripts/unifdef - .config - *.o - .*.cmd Avoid copying files twice for the following directories: - include/generated/ - arch/*/include/generated/
