evdev: check model flags for actual booleans

The hwdb doesn't allow unsetting a property so once we start nesting model
flags it'll become important to be able to be able to unset one as well (by
assigning it to 0).

So rather than checking for existence, check whether the property is actually
set to something resembling a boolean.
