chg: fallback to original hg if stdio fds are missing
If stdio fds are missing (ex. fd 0 is not present), chg might open
fds that take the numbers 0, and attachio would send the wrong fds
to the client, which might cause unwanted behaviors. Avoid that by
detecting the missing fds and falling back to the original hg.
