[LEDE-DEV] [PATCH] base-files: sysupgrade. Added the ability to use URL as source

From: Sergey Sergeev <adron at yapic.net>

I did not encapsulate the logic in get_image() because too much code
(like dd if=...) expects to work with the file instead of url. And
use get_image would lead to repeated data reloads from url.
