selftests: mptcp: close server file descriptors

The server file descriptor ('fd') is opened in server() but never closed.
While accepted connections are properly closed in process_one_client(),
the main listening socket remains open, causing a resource leak.

This patch ensures the server fd is properly closed after processing
clients, bringing the sockopt and inq test cases in line with proper
resource cleanup practices.
