Maniphest Tasks: T13675: Can Arcanist plausibly be compiled into a binary?
Commits: rARCfc5b228db537: Return STDIN, STDOUT, and STDERR file descriptors from parent process

Summary

Ref T13675. When a process daemonizes, it needs to close these actual file descriptors, so the calling context must provide them.

Elsewhere, modify the embedded "arc" to provide them. Then use them in place of reopening the streams.

Test Plan

Ran locally with embedded "arc", will deploy for production hangs.
