When reloading the dbus-broker service (e.g. when switching to a new generation),
the reload fails when /tmp got remounted after the service had been started.
Since the dbus-broker service starts early, and does not have default dependencies,
this situation does occur in practice.
This change makes sure that if there are mount units for /tmp, dbus-broker gets
ordered after them.

This makes sure we don't need any workarounds for running Invidious with a local
PostgreSQL database.
Changing the default user should be fine as the new init script for PostgreSQL automatically
creates the new user and changes the existing database's owner to the new user. The old user
will still linger and must be removed manually.

This simplifies the setup to receive emails from the ZFS Event Daemon
by relying on the sendmail wrapper defined by other modules such as
msmtp or Postfix.
This is more similar to how other modules like smartd deal with email
configuration.
The user is no longer required to define and rebuild their own ZFS
package to add email support.

This fixes a panic of the kubo daemon which could occur under certain conditions when the daemon was starting.
It was caused by the `ipfs.service` unit not depending on the `ipfs-api.socket` and `ipfs-gateway.socket` units with `Wants=`. This allows the `ipfs.service` to be started manually or by `nixos-rebuild` without the sockets being set up before that. When that happens, the daemon won't know about these sockets and will only use what is set in `services.kubo.settings.Addresses.Gateway` and `services.kubo.settings.Addresses.API`. By default the `API` is an empty list in NixOS though. The daemon doesn't like this at all and panics on startup, see https://github.com/ipfs/kubo/issues/10056.
With this commit, starting `ipfs.service` will first set up the two sockets before starting the actual service.
Adding the `Sockets=` option implicitly adds a `Wants=` for the sockets and this is exactly what we need. See https://www.freedesktop.org/software/systemd/man/latest/systemd.service.html#Implicit%20Dependencies . This can be checked with `systemctl show ipfs.service`.
This should probably be upstreamed to the unit file in the Kubo repo.
The problem can be reproduced in the following way:
- Add `services.kubo.enable = true` to `/etc/nixos/configuration.nix`
- `sudo nixos-rebuild switch` (this may already fail, not sure why it's not deterministic for me)
- `sudo systemctl stop ipfs-api.socket`
- `sudo systemctl stop ipfs-gateway.socket`
- `sudo systemctl stop ipfs.service`
- `sudo systemctl start ipfs.service`
Fixes#248447.
