proxmox-mail-forward is a new helper binary in Rust intended to behave
essentially the same on PVE installations. It can also handle mixed
PBS+PVE installations.

Signed-off-by: Fiona Ebner <f.ebner@proxmox.com>

The downside with this approach is that a downgrade of
pve-manager will re-introduce the pvemailforward entry in .forward,
which means duplicate mails (except proxmox-mail-forward is removed
again at the same time).

An alternative would be using a Breaks on pve-manager:
1. don't touch .forward in pve-manager's postinst anymore
2. have proxmox-mail-forward break older pve-manager
3. have proxmox-mail-forward's postinst replace the entry in .forward
