qemu-sanity-check.in: Use '-display none' instead of '-nographic'

Upstream QEMU recommends to use '-display none' as opposed to
'-nographic' -- which is a "legacy option that does a whole bunch of
confusing stuff" (thanks Peter Maydell).

Upstream libguestfs already made the switch [1] in DEC-2013.

    switch from -nographic to -display none "
