diskinfo(8): introduce new option -l
In modes -p or -s, add an option -l to start each line with a device name separated with a tab. Update the manual page. Add an example to list names with corresponding serial numbers: diskinfo -ls /dev/da? (cherry picked from commit e333110d1de748e50051d1305b5438d1bc54eeb4)
