tests: rename target_big_endian() as qvirtio_is_big_endian() 

Move the definition to libqos/virtio.h as it must be used
only with virtio functions.

Add a QVirtioDevice parameter as it will be needed to
know if the virtio device is using virtio 1.0 specification
and thus is always little-endian (to do)
