[Buildroot] [PATCHv3 04/18] pkg-download: remove support for the SHOW_EXTERNAL_DEPS DL_MODE

[Thomas Petazzoni]

Now that the external-deps implementation relies on the per-package
<pkg>-all-external-deps and <pkg>-external-deps targets and no longer
on the 'source' target with a custom DL_MODE, we can get rid of the
support for the SHOW_EXTERNAL_DEPS DL_MODE value in the pkg-download
logic.
