MDEV-28648 main.ssl_timeout fails with OpenSSL 3.0.3

Depending on OpenSSL version, and at least in 3.0.3, the client-side socket
timeout is reported as generic error (SSL_ERROR_SYSCALL), losing further
details (both errno and GetLastError() return 0). This results in client
reporting "Unknown OpenSSL error" 2026, instead of another generic
"Lost connection to server during query" 2013

Adjusted test case.
