selftests/vsock: skip vng setsid workaround on >= 1.41

Browse Source 
virtme-ng 1.41 ships the upstream fix for the SIGTTOU hang
(https://github.com/arighi/virtme-ng/pull/453), so the setsid wrapper in
vng_dry_run() is no longer needed there. Gate the workaround on the vng
version: setsid is used for vng < 1.41, and vng is invoked directly on
>= 1.41.
