What does this PR try to resolve?

#10738 introduced a regression where build scripts did not close stdin, causing deadlocks for build scripts waiting for stdin.

Fixes #11196 by not piping stdin unless requested by the ProcessBuilder.

How should we test and review this PR?

Run a build script that reads from stdin and check that it no longer hangs. See the POC in the linked issue. The included test hangs without the fix.

We may want to beta backport this.

This does blow away the deadlock, but I am not sure whether to keep stdin piped by default. Probably not?

Okay, I reworked it to avoid opening stdin as piped unless explicitly requested.

Looks good to me.

I wonder if it needs a patch version bump, as it contains no-breaking change only.

@ehuss, do you have any opinion on this patch?

And yea, if you don't mind, can you post a PR to the rust-1.65.0 branch to backport this?
