libcamera: ipc_unixsocket: Don't send uninitialized bytes over the socket
IPCUnixSocket::send() sends a IPCUnixSocket::Header allocated on the stack. All the fields of the header are initialized, but the padding bytes are not. This results in random data being sent over the UNIX socket, potentially leaking information. Fix this by initializing the whole header to 0.
