[Buildroot] [PATCH v2 1/6] support/download: Add support to pass options directly to downloaders

[Romain Perier]

This adds support to pass options to the underlying command that is used
by downloader. Useful for retrieving data with server-side checking for
user login or passwords, use a proxy or use specific options for cloning
a repository via git and hg.

Changes in v2:
 - Replaced the variable $(PKG)_DL_REFERER by $(PKG)_DL_OPTS
 - Add modification to all downloaders
