Added fake touchscreen daemon to make builtin apk work

Several Android builtin packages would pick up the system resources
about touchscreen.  If there is no touchscreen, the ones suffixing
with '-notouch' would be taken.  However, by default, resource layout
doesn't come with '-notouch', and Beagleboard has no touchscreen on
board physically.  Thus, Android core will crash due to lacking of
proper resources.

Our solution is to write a dedicated daemon to register userspace
input device as a fake touchscreen device.  EventHub would regard
it as one of the input source, and no Android packages would complain.

DO NOT MERGE: Demo purpose only.

Running faketsd before system runs and Android will think the system
having resource of touchscreen, and will try to access resource of
fingers.
