glimmer : Bring in touch-control script from link
We used this optional script in the Link overlay to disable acpi wakeups
for touchscreen and touchpad from the power manager. This provided
an extra level of protection from spurious wakes.
(see crbug.com/224255).
Lets bring this back for Glimmer, and have it unconditionally
disable the touchscreen, in case the wakeup int is floating.
