[pve-devel] [PATCH installer] tree-wide: add serde `derive` where actually needed

[Christoph Heiss]

Fixes building each crate on their own.

In a full build (e.g. `make deb`), everything pulls in serde with the
`derive` feature anyway and thus does not exihibit any build failures.

Only noticed this by pure chance while using `cargo test -p
proxmox-tui-installer`. Interesting though that a full build does not
break, which is why I didn't notice it until now ..
