[pve-devel] [PATCH installer v2 07/17] debian: strip unused library dependencies

[Christoph Heiss <c.heiss@proxmox.com>]

Rust links in some dynamic libraries even if only used by a disabled
feature gate.

This will be needed due to moving http-related code into the
proxmox-installer-common crate and thus pulling it in at more places.
