Update fetchmail to selfbuilt 7.0.0-alpha

Fetchmail in alpine is ~5 years old — and doesn’t support current SSL/TLS
variants anymore. This especially leads to our own fetchmail not being able to
pull mail from mailu itself. Since no new fetchmail release is on the horizon,
let’s build the lastest distribution artifact — which strangely is not
6.4.0-snapshot, but 7.0.0-alpha — ourselves.
