Dockerfile: add "feeds.conf" to "imagebuilder" too

[lars18th]

Hi,

The official docker image could be used with the feed scripts (./scripts/feeds) to compile custom packages. However, is quite annoying that the small text file feeds.conf is missing. And this generates a lot of troubles if you don't know why the docker image fails to execute the feed scripts.

So, I suggest to add the default file described in the documentation (https://openwrt.org/docs/guide-developer/feeds):

src-git packages https://git.openwrt.org/feed/packages.git
src-git luci https://git.openwrt.org/project/luci.git
src-git routing https://git.openwrt.org/feed/routing.git
src-git telephony https://git.openwrt.org/feed/telephony.git
#src-git video https://github.com/openwrt/video.git
#src-git targets https://github.com/openwrt/targets.git
#src-git management https://github.com/openwrt-management/packages.git
#src-git oldpackages http://git.openwrt.org/packages.git
#src-link custom /usr/src/openwrt/custom-feed

I hope you agree with that. Regards.

You can't compile packages with the imagebuilder but only the SDK, why would you want feeds (aka uncompiled package definitions) in the ImageBuidler?

Yes, you're right. Only the SDK could be used to compile packages.

Perhaps this sounds stupid, but I suggest to put some README file inside the "imagebuilder" container image to describe the "target use". And recommend inside it to use the "SDK" to compile packages. I feel other users will be confused by the different images.

Anyway I close this issue. Thank you @aparcar.
