[Buildroot] [PATCH 5/7] pkg-generic: allow full URLs for <pkg>_EXTRA_DOWNLOADS

[Thomas Petazzoni]

The current logic for <pkg>_EXTRA_DOWNLOADS assumes that it is a list
of files, all hosted at <pkg>_SITE. However, just like for
<pkg>_PATCH, it may be useful to specify <pkg>_EXTRA_DOWNLOADS entries
that are hosted on a different site than the package <pkg>_SITE.

This commit implements this, by re-using the same logic as the one
used for <pkg>_PATCH.
