hw/virtio: Move vhost-user-input into virtio folder

vhost-user-input is in the input folder.  On the other hand, the folder
'hw/virtio' maintains other virtio stubs (e.g. I2C, RNG, GPIO, etc).

This patch moves vhost-user-input into the virtio folder for better code
organization.  No functionality change.
