[PATCH] Add Docker build support Export this patch

From: Timur Demin <me@tdem.in>

This adds a Dockerfile and a short instruction on how to use it to run
Satellite. Since the Makefile requires scdoc to be installed (which is
not present in golang:1.15), the Dockerfile runs go build manually
instead.

Sent this as a new patch due to master branch heavily diverging with what my 
local copy turned into by 3 commits (not sure of the cause).

Notably a little overdue. :)

Hi there,

Thanks for the patch!

Sorry about the branch divergence, had to do a rebase because I fucked
up some commits.

To git.sr.ht:~gsthnz/satellite
