Leo Yan bad38726e9 hw/virtio: derive vhost-user-input from vhost-user-base
This patch derives vhost-user-input from vhost-user-base class, so make
the input stub as a simpler boilerplate wrapper.

With the refactoring, vhost-user-input adds the property 'chardev', this
leads to conflict with the vhost-user-input-pci adds the same property.
To resolve the error, remove the duplicate property from
vhost-user-input-pci.
