Official arm/rpi docker image

[schvabodka-man]

Hello, there are currently only gitea images for x86. Would be cool if someone would build one for arm platforms. Gogs, for example has seperate image for rpi

It's not official, but this container is built (with sqlite support) for arm and is running on my rpi3.

a multi-arch manifest on the Hub would be a nice topping on this.

@funkyfuture I plan to do a multi-arch setup (allready had but I separated it to ease the review process). Now, I wait for #2927 to be merged to go to next phase multi-arch.

This is a dupe of #531

Can this issue be closed?
