[Bug] QMK doctor only checks /etc/udev/rules.d for udev rules.

The doctor command in qmk python library fails to find the correct rules in /usr/lib/udev/rules.d directory.

Describe the Bug

The doctor command in QMK python library only checks a hard coded /etc/udev/rules.d for udev rules. Which works fine if you put your rules there. But these rules can also be located in /usr/lib/udev/rules.d; and actually is the preferred location for linux package managers to drop their udev rules. I recently packaged the python client in archlinux; and also provided neccessary udev rules along with it. After switching to these rules, I noticed I was getting warnings from qmk doctor when I had the correct udev rules in place.
