* feat: use go1.16 embedding for resources
We want to embed everything that can be easily embedded. We should, at a
minimum, replace the downloading of resources and bindata.
Ref: https://github.com/ooni/probe/issues/1367.
* fix: get rid of bindata and use go embed instead
* fix: start unbreaking some automatic tests
* fix: fetch resources as part of the mobile build
* fix: convert more stuff to go1.16
I still expect many breakages, but we'll fix them.
* fix: make the windows CI green
* fix: get resources before running QA
* fix: go1.16 uses modules by default
* hopefully fix all other outstanding issues
* fix(QA/telegram.py): add another DC IP address
* Apply suggestions from code review
* refactor: build miniooni from toplevel
Of course, also move the specific test checking whether we are
still able of building miniooni.

* build for current branch just to confirm
* fix: correct the path where linux/arm binary is
* okay, it works, we can remove the special rule
