John Ericson b41cc1a755 Make wrapper derivation
This ensures just `nix build`-ing the flake doesn't forget to run all
tests. One can still specifiy specific attributes to just build one
thing.

Whether to perform a "quick" build of the Nix package to test.
When iterating on the functional tests, it's recommended to "set" this
to `true`, so that changes to the functional tests don't require any
recompilation of the package.
You can do so by building the `.quickBuild` attribute on the check package,
e.g:
```console
nix build .#hydraJobs.functional_user.quickBuild
```
We don't enable this by default to avoid the mostly unnecessary work of
performing an additional build of the package in cases where we build
the package normally anyway, such as in our pre-merge CI.
