We're starting to prepare a new release. The first step is to use
go1.17.6 in the following places:
1. everywhere we define the version of Go in this tree;
2. when we're building for Android (using ooni/go);
3. in our ooni/oohttp fork of Go net/http standard library.

Original commit message:
- - -
This pull request changes `mk` and github workflows to build and publish binaries on tag. We also update the documentation to explain this new branching model. Basically, we have release branches where we produce binary packages and we add extra code, on tag, to publish such packages inside a release.
We discussed removing most secrets from builds in this repository and having a different tool/repository that takes in input also secrets for doing follow-up actions after publishing. As a consequence, this pull request also removes all pieces of code that require secrets. The next step is to reinstate this code in this new repository/tool.
The existing code in `mk` also implemented caching. This feature was useful when doing local builds because it reduced the time required to obtain binary releases. With builds running as part of GitHub actions, we don't need caching because we spawn parallel machines to build binaries. Therefore, let us also remove caching, which makes the code simpler. (Caching in itself is hard and in https://github.com/ooni/probe/issues/1875 I noted that, for example, caching of the `ooni/go` repository was leading to some unwanted behaviour when changing the branch. Without caching, this behaviour is gone and we always generally use fresh information to produce builds.) Of course, this means that local builds are now slower, but I do not think this is a problem _because_ we want to use GitHub actions for building in the common case.
Reference issues: https://github.com/ooni/probe/issues/1879 and https://github.com/ooni/probe/issues/1875.
The final aspect to mention to conclude this description is an implementation one:
```
gh release create -p $tag --target $GITHUB_SHA || true
```
The code above uses `|| true` because there could already be a release. So, basically, it means that, if a release does not already exist, then we're going to create one. Otherwise, it does not matter because there's already a release.

Original commit message:
- - -
- ensure we use go1.17.3 in workflows
- update to a version of ooni/oohttp that uses go1.17.3
This change WILL need to be forward ported to master.
Closes https://github.com/ooni/probe/issues/1861
