switch to using the upstream nixos mattermost module

this does start up correctly, creating its state directory and so on.

it isn't yet world-visible, because we don't have the SSO set up yet.
that's likely to make testing it difficult, which is unfortunate but
necessary, since there's no way it's secure.
