This is a small change, but I don't know why this functionality is buried so
centrally in the first place.  It should be picked up as a dependency by the
things we are compiling on the target, but not by any of the host pieces.


TODO to refactor this?

[Dirk Pranke, 2015-09-03 21:28:24]

Can you just do the refactoring and move the evdev logic out of
//build/config/linux and //build/config/ui.gni and into //ui/events/ozone ? 

It looks like that's the only place that uses it.

Handing over to spang because my build-fu is weak.
