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/
