[Buildroot] [PATCH 1/3] package/pkg-generic: allow to use <pkg>_DL_VERSION in packages .mk files

[Victor Huesca]

This patch continue the work done here http://buildroot-busybox.2317881.n4.nabble.com/PATCH-0-4-Sanetize-packages-version-tp225554.html
By making this DL_VERSION public we should be able to handle the missing corner-cases
with package version sanitizeing.
