[Buildroot] [PATCH 10/11 v5] package/nvidia-tegra23-binaries: provides JPEG

[Nicolas Serafini]

Yann, all,

I'm not able to build a package that has dependency on libjpeg because
headers are missing.

The Nvidia documentation doesn't not provide any information on this
binary version of libjpeg so for me we have two choice.

The first is to add a patch that provide headers and the second is to
simply remove this patch.
It's possible to use accelerated jpeg using jpeg-turbo and the BSP I
was using before simply drop this binary version of libjpeg.

Nicolas
