On Fuchsia, spawning a subprocess does not automatically clone all of the parent process' capabilities. UTC time on Fuchsia is managed by a top-level userspace clock capability that is cloned and passed to subprocesses. This change ensures that any Rust subprocess gets access to the UTC clock, if the parent had access to it. This is critical for tests, which on Fuchsia, use panic=abort and spawn subprocesses per test.
