Revert "[2/2] Framework/base: Configure headset hook"

Toggling whether the headset button works or not is like
    "toggling whether or not the volume buttons do anything"...
    especially with the default being to do nothing with it pressed.

find me a user that is bothered by their headset button doing what they expect
     when they press it, and I'll consider revisiting this.

This reverts commit 601f544a2211c1ceacca8dae906d8bc67e828463.
