[Buildroot] [PATCH 6/8] odoridc2: add mainline post image script.

[Dagg Stompler <daggs@gmx.com>]

the mainline image doesn't have the signed firmwarfe bundled in the
uboot images.
to address this issue, the needed files are required to be retrieved
from the vendor's site, prepared and embbeded into the final image.
