util/find_usbdebug: Fix lsusb -t parsing for usbutils v016 and newer

Commit e24294ff9ade ("lsusb -t: print ports and busses and devices with
same width") [1] in the usbutils repository changed the format of the
lsusb -t output, breaking the find_usbdebug.sh script. This commit is
present in usbutils version 016 and later.

Use the output of lsusb -V to determine the version and set the bus/port
parsing patterns accordingly to fix lsusb -t parsing for newer versions
of usbutils while maintaining compatibility with older versions. A
simple integer comparison of the version number is used, which will not
work with versions of usbutils older than v001 which used a 0.nn version
numbers. However, the newer version number format has been used since
2010, so it is probably safe to assume that no one will be using a
version of usbutils older than that.

TEST=find_usbdebug.sh works as expected with both lsusb v015 and v017
