Dimitris Aragiorgis 3307ed7b3f raw-posix: Introduce hdev_is_sg() 
Until now, an SG device was identified only by checking if its path
started with "/dev/sg". Then, hdev_open() would set the bs->sg flag
accordingly. The patch relies on the actual properties of the device
instead of the specified file path.

To this end, test for an SG device (e.g. /dev/sg0) by ensuring that
all of the following holds:

 - The specified file name corresponds to a character device
 - The device supports the SG_GET_VERSION_NUM ioctl
 - The device supports the SG_GET_SCSI_ID ioctl
