target: Implement Block Device Characteristics VPD page
Implement page B1h, Block Device Characteristics, so that we can report a medium rotation rate of 1 (non-rotating / solid state) if the is_nonrot device attribute is set; we update the iblock backend to set this attribute if the underlying Linux block device has its nonrot flag set.
