Put functional tests in tests/functional

I think it is bad for these reasons when `tests/` contains a mix of
functional and integration tests

 - Concepts is harder to understand, the documentation makes a good
   unit vs functional vs integration distinction, but when the
   integration tests are just two subdirs within `tests/` this is not
   clear.

 - Source filtering in the `flake.nix` is more complex. We need to
   filter out some of the dirs from `tests/`, rather than simply pick
   the dirs we want and take all of them. This is a good sign the
   structure of what we are trying to do is not matching the structure
   of the files.

With this change we have a clean:
```shell-session
$ git show 'HEAD:tests'
tree HEAD:tests

functional/
installer/
nixos/
```

For example, this technique is used for the language tests, to check both the printed final value if evaluation was successful, and any errors and warnings encountered.
It is frequently useful to regenerate the expected output.
To do that, rerun the failed test with `_NIX_TEST_ACCEPT=1`.
(At least, this is the convention we've used for `tests/lang.sh`.
If we add more characterization testing we should always strive to be consistent.)
To do that, rerun the failed test(s) with `_NIX_TEST_ACCEPT=1`.
For example:
```bash
_NIX_TEST_ACCEPT=1 make tests/functional/lang.sh.test
```
An interesting situation to document is the case when these tests are "overfitted".
The language tests are, again, an example of this.
