Various build improvements

[dmacvicar]

• Switch to using go modules
  • go builddoes the right thing
  • Note: I did not check go.sum in, but it can also be done
• Use go-bindata via go generate
  • go-bindata is fetched as any other dependency
• Decouple build logic from the container
• Allows to build the same without the container. Put the logic in a Makefile and use that in the container
• Note that in any case there is no need for go getanymore

With six open PRs, and no much happening, I am afraid the developer(s) aren't much active, if at all. 😢

This project seems dead, and the maintainer its obviously missing, as proposal:

https://github.com/subspacecommunity/subspace

@dmacvicar I'm creating this and accepting any PR that seems logic, can I merge this fixes? or maybe do the PR e. I guess I'll spam this to all the other PRs.

Thanks for merging those!
