Take advantage of lazy bindings by not requiring runtime dependency.

Up to and including Rust 1.27.x, the Rust build system shelled out to
a configure script to detect the presence and usability of libunwind.
Since Rust 1.28.0, it's using a static result in a `build.rs` file and
expects libunwind to be used. It was not the case on FreeBSD so far, so
we need a patch to this `build.rs` to disable that. We still need to
study if the FreeBSD port should use libunwind and what to do with this
patch. But this problem prevented the update to Rust 1.28.0 already, so
enough delay.
