selftests: mptcp: close server IPC descriptors
The client-side function connect_one_server() properly closes its IPC
descriptor after use, but the server-side code in both mptcp_sockopt.c
and mptcp_inq.c was missing corresponding close() calls for their IPC
descriptors, leaving file descriptors open unnecessarily.
This change ensures proper cleanup by:
1. Adding missing close(pipefds[0]/unixfds[0]) in server processes
2. Adding close(pipefds[1]/unixfds[1]) after server() function calls
This ensures both ends of the IPC pipe are properly closed in their
respective processes, preventing file descriptor leaks.
