flare messenger needs Secret Service provider

[Mikolaj Kucharski]

Hi,

I wanted to test Flare messenger, but it errors with:

        The communication with libsecret failed.

```
DBus(
    Service(
        ZBus(
            MethodError(
                OwnedErrorName(
                    "org.freedesktop.DBus.Error.ServiceUnknown",
                ),
                Some(
                    "The name org.freedesktop.secrets was not provided
by any .service files",
                ),
                Msg {
                    type: Error,
                    serial: 3,
                    sender: UniqueName(
                        "org.freedesktop.DBus",
                    ),
                    reply-serial: 4,
                    body: Str,
                    fds: [],
                },
            ),
        ),
    ),
)
```

I'm wondering how this could be more exposed to the user? Package
readme?

I'm not sure what lightweight choices for Secret Service providers are
in ports, as the KDE / GNOME ones are too heavy for my taste. Do you
guys have any advise?
