fix #4788: build static version of client

Fixes: https://bugzilla.proxmox.com/show_bug.cgi?id=4788

Build and package the a statically linked binary version of
proxmox-backup-client to facilitate updates and distribution.
This provides a mechanism to obtain and repackage the client for
external parties and Linux distributions.

The statically linked client is provided as dedicated package,
conflicting with the regular package.

Since the RUSTFLAGS env variables are not preserved when building
with dpkg-buildpackage, invoke via `cargo rustc` instead which allows
to set the recquried arguments.

Credit goes also to Christoph Heiss, as this patch is loosely based
on his pre-existing work for the proxmox-auto-install-assistant [0],
which provided a good template.

Also, place the libsystemd stub into its own subdirectory for cleaner
separation from the compiled artifacts.
