evdev: Enable the compilation of the evdev backend for eglnative

Not tested (but checked that it compiles).

There's no reason to only enable the check for the cex100. Hopefully
should work.

We make sure not to enable both the evdev and the tslib backend at the
same time as the DeviceManager is a singleton and we can't have both
subclasses at the same time for now.
