lsusb -t: print ports and busses and devices with same width

lsusb shows values in 3 digit fields, so do the same for 'lsusb -t' as
well, making it more obvious what device matches up with what.

This also mirrors the output of the -vv option as well, which shows that
the kernel uses 3 digits for these values in /dev/bus/usb/
