scsi: add fallback definitions for SG_* ioctl command constants

Browse Source 
Unfortunately, <scsi/sg.h> from libc does not provide all constants
recognized by the kernel.

* xlat/scsi_sg_commands.in: New file.
* scsi.c: Include "xlat/scsi_sg_commands.h" instead of providing
a fallback definition of SG_IO.
