[PATCH pve-cluster 05/10] buildsys: link pmxcfs against the rust notify staticlib

[Hannes Laimer <h.laimer@proxmox.com>]

Only the daemon binary links the Rust staticlib, while the database
tools and the unit tests keep linking the plain C convenience library.
Building it from here as well keeps a standalone make in src/pmxcfs
working and picks up Rust changes without a manual step.
