[pve-devel] [PATCH installer 07/14] debian: strip unused library dependencies

[Christoph Heiss]

Rust links in some dynamic libraries even if only used by a disabled
feature gate. This is needed due to the upcoming move of the HTTP
features into the `proxmox-installer-common` crate.

Very similar to how it is done in the `proxmox-backup` repository, which
needs the same for very similar reasons.
