provide Linux kernel input device so kloak (anti keystroke deanonymization tool) can be used in Qubes-Whonix

[adrelanos]

kloak (anti keystroke deanonymization tool) currently cannot be used inside Qubes.

quote @marmarek:

Hmm, I was under impression it expect X server input device, not not Linux kernel input device. Qubes GUI agent do not expose the later. It shouldn't be hard to change that, but still it is some code change. Namely, rewrite this function (feed /dev/uinput instead of X input device).

The kloak project was recently active with lots of code improvements.

Should this be merged into #1850?
