[Buildroot] [PATCHv3 2/5] core: allow external Config.in/makefile code to be integrated

This commit allows the BR2_EXTERNAL directory to contain additional
Buildroot packages:

 - Buildroot automatically includes the
   $BR2_EXTERNAL/package/Config.in in the "Target packages"
   configuration sub-menu.

 - Buildroot automatically includes the BR2_EXTERNAL/package/*/*.mk
   files in the build logic.

We also add a dummy Config.in file in support/dummy-external/ to
ensure that the source "$BR2_EXTERNAL/Config.in" line will point to an
existing file even when BR2_EXTERNAL is not used by the user.
