It doesn't seem like it should be necessary but it helps, a little, I think.

It's not clear to me why passing `buildPackages.python3` as the value for
`python` to the `override` call isn't the way to do this.  If we take that
approach then the configure phase fails because it cannot find "python".

It is an Android of some sort.

So none of the newer-compiler-stdenvs nixpkgs offers can help us here.

The newer tahoe-chk drops the text-format dependency which pulled in many
other complex libraries as transitive dependencies.

This fixes one build error on Android, at least.

The stdenv version isn't new enough for Botan or Boost or something.

Also replace the rest of the GitLab boilerplate content with some real
details.

It does not follow / dereference symlinks, which is a problem with Nix.

See:

> This is also relevant for Nix builds, since it creates a ./result symlink to /nix/store/<somewhere>.

The earlier package name made the build fail:

> FAILURE: Build failed with an exception.
> * What went wrong:
> Execution failed for task ':processDebugResources'.
>> Package 'storage.private.privatestoragemobile' from AndroidManifest.xml is not a valid Java package name as 'private' is a Java keyword.

This is what current stable Obelisk running on NixOS 22.11 gives me.
I.e. `ob init` in this folder.

Refs #10.

Fixes #8.
