fs/promises: fix fd resource cleanup

[bnoordhuis]

Untested, but the existing code looks just plain wrong - the more so because line 403 does call fs.close.bind(fd).

[cjihrig]

Looking at git blame, it looks like d00d81e intentionally removed the bind() calls.

Suggested change

	return fchmod(fd, mode).finally(fd.close.bind(fd));
	return fchmod(fd, mode).finally(FunctionPrototypeBind(fd.close, fd));

[mscdex]

Is there a way we can add a test for this?

Right, I did see that commit and I understand how it works but it doesn't look Obviously Right to me. But if other people feel it's great idea, then the thing to do is to at least be consistent. I've changed it to remove the .bind() call on line 403.
