Greg Kurz 354b86f85f tests: virtio-9p: add WRITE operation test
Trivial test of a successful write.

Signed-off-by: Greg Kurz <groug@kaod.org>
(groug, handle potential overflow when computing request size,
        add missing g_free(buf),
        backend handles one written byte at a time to validate
        the server doesn't do short-reads)
