[roll] Roll fuchsia [starnix][kernel] Clarify get_waitable_child result

Previously, this function returned a `Result<Optional<...`, which made
it unclear what the difference was between an error result and an
`Ok(None)` result. This CL changes the function to return a custom enum
that makes the `ShouldWait` and the `NoneFound` cases clear.

This clarity is especially useful for the one caller, which previously
intercepted the `Err(...)` result and sometimes did not generate an
error (i.e., in the case where it had a tracee to wait for).
