This adds missing commands to the table from SBC and related standards.
Only commands that affect the medium are added. Commands that affect
other state of the LUN are all privileged, with the sole exception of START
STOP UNIT (which has always been allowed for all file descriptors. I do not
really agree with that and it's probably an artifact of when /dev/cdrom had
r--r--r-- permissions, but I'm not trying to change that.
