tests/unit: Add unit tests for fill_vdi_state_list()

The function fill_vdi_state_list() implementing SD_OP_GET_VDI_COPIES
should set the 'deleted' member of struct vdi_state and respond it.

This is mainly for sheep/group.c:get_vdis_from() because it set
VDI bitmap 'sys->vdi_deleted' based on the value of 'deleted' member
responded by SD_OP_GET_VDI_COPIES request.
