Add just enough support for static key so that we can use it from
tracepoints. Tracepoints rely on `static_key_false` even though it is
deprecated, so we add the same functionality to Rust.

This static key code is something that can be generally useful
both in kernel and user-space. Is there anything that would prevent
licensing this under MIT right away instead so it could eventually be
re-used more broadly in userspace as well ?
Thanks,
