Fix ExecUtils.WaitChildWithTimeoutFallback by adding a fallback.
`WaitChildWithTimeout` didn't work with old Linux kernels because it
uses a syscall `pidfd_open`, which was added in Linux 5.4.
This change adds a fallback implementation of `WaitChildWithTimeout`
that creates a thread to wait instead of relying on `pidfd_open`.
Also:
- Use android::base::unique_fd to hold pidfd so that the fd is
guaranteed to be closed.
- Allow timeout_sec to be negative, in which case it blocks until the
subprocess exits.
