Fixing FindUnusedPort method tcp_socket object creation with proper constructor parameter (#121879)
### Issue:
Currently lldb `platform connect unix-connect://localhost:43045/` is
failing and showing "Failed to connect port" error message.

### Cause:
TCPSocket(bool should_close, bool child_processes_inherit) constructor
was removed in commit
[c1dff71](https://github.com/llvm/llvm-project/commit/c1dff7152592f1beee9059ee8e2cb3cc68baea4d#diff-91817651b505a466ea94ddc44eca856f62073e03b05d0d0d2f4a55dcfea0002eL20).
However, the tcp_socket object creation still passes the deleted
constructor parameters, which causes the invocation of the wrong
constructor. As a result, the `FindUnusedPort` method is unable to
resolve the local port and always returns 0.
