[Buildroot] [PATCH v2] Add support for plain URL in $(PKG)_PATCH variable

["Jérôme Pouiller" <jezz@sysmic.org>]

Until now, $(PKG)_PATCH allow only to download patches from same URL than tarball.
This patch allow to detect when plain URL are used in $(PKG)_PATCH and correctly
handle them.

Signed-off-by: J?r?me Pouiller <jezz@sysmic.org>

v2: 
  - Rebase to apply to HEAD
  - Drop patch called "Add $(PKG_NAME) in name of downloaded patches" since I am
    not personally convinced of its usefulness
