udev: add input/by-{id,path} symlinks for hidraw devices

Browse Source 
Take some of the same rule structure from 60-persistent-input.rules, and
apply it to hidraw devices in 60-persistent-hidraw.rules.

Since one of the motivations for this is being able to easily reference
FIDO tokens, add a special case when ID_FIDO_TOKEN==1, and add 'fido'
to the symlink.
