Set MAC based name for USB network interfaces only for universally administered (i. e. stable) MACs

Browse Source 
Stop doing this for locally administered (i. e. randomly generated) ones. These
devices have no intrinsic stable properties, so use the default location based
names for those.

Drop /lib/systemd/network/90-mac-for-usb.link (as link files don't currently
support globs for MACAddress=) and replace with an udev rule in
/lib/udev/rules.d/73-special-net-names.rules.
