[PATCH v2 1/2] stubs/monitor: add monitor_fd_param()

[Stefano Garzarella <sgarzare@redhat.com>]

The blkio block driver will use monitor_fd_param() to support
file descriptor passing. This is possible in builds (e.g. softmmu)
where the monitor API is available.

Add the monitor_fd_param() stub so tools and tests that link the
block layer can build successfully.

    v2:
