Fix missing return after accept4 failure in InteropServer::Accept

[benhillis]

When accept4 fails in InteropServer::Accept, the function logs an error but falls through to call setsockopt on the invalid file descriptor (-1) and returns it to the caller.

This return {}; exists on master (added in 040f5e4) but was lost during a merge into feature/wsl-for-apps.

Fix: Add the missing early return {}; to match master behavior.

Pull request overview

This PR restores the missing early return {}; in InteropServer::Accept() on accept4() failure to avoid calling setsockopt() on an invalid fd and returning it to callers (aligning behavior with master).

Changes:

• Add an early return {}; when accept4() fails in InteropServer::Accept().
• (Unrelated) Add CloudTest/TAEF run outputs and system logs under GeneralAttachment/.
