mautrix-meta: 0.3.2 -> 0.4.0

This update cannot be done by the nixpkgs bot, as
the structure of the project has been changed, so why wait.

The mautrix-meta project has been moved under "cmd/mautrix-meta"
There is also "cmd/lscli", but since this package is mainly
about mautrix-meta, I think we can stay with this specific cmd.
If we wanted, we could switch to both of them by removing this
`subPackages` attribute.
