Fix #63 (without using `--attribute-walk`)
Fix #63 (without using `--attribute-walk`)

Use a more precise query for udev info that expands the number
supported platforms.
Possibly closes #63 by specifying a more clearly defined query that
obviates the need to parse the output of `--attribute-walk`.
Recent udevadm versions use `--query=all --export` as a default action
while older versions do not.
