[pbs-devel] [PATCH proxmox-backup 1/2] build: ensure wrapper config is picked up

[Fabian Grünbichler]

`cargo build` and `cargo install` pick up different config files, by symlinking
the wrapper config into a place with higher precedence than the one in the
top-level git repo dir, we ensure the package build actually picks up the
desired config instead of the one intended for quick dev builds.
