buildsys: workaround linkage issues from openid/curl build server stuff separate

this blows up build times, but we do not plan for using it longer
than required (i.e., the server is finally split into its own binary
crate providing only those binaries).

Note, using `cargo b --release` to build is naturally unaffected by
this change, so for dev builds just continue to use that.
