[Buildroot] [git commit] Makefile: use the package infra based external-deps

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=7e679ccb4c10b653839c3b8cea233a96d8556a5b
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This commit changes the global 'external-deps' target to use the newly
introduced per-package <pkg>-all-external-deps, instead of relying on
the 'source' target with a custom DL_MODE.
