[pve-devel] [RFC PATCH installer] buildsys: add static version of proxmox-auto-install-assistant

[Christoph Heiss]

This adds a separate debian package to the build, containing a
statically-built version of `proxmox-auto-install-assistant`, as
was suggested in #4788 [0] (for proxmox-backup-client), separately by 
Thomas also.

Rust nowadays makes building static binaries pretty easy, even when
OpenSSL etc. is used.

NB: When run through lintian, the resulting package produces the
`shared-library-lacks-prerequisites`, which overalls seems rather
irrelevant (or even bogus?) in our case [1].

Marked RFC to see if the packaging is overall sane -- I haven't done a
lot of (Debian) packaging yet, so please don't hesitate with
suggestions.
