lmkd: Fix usage of ro.lmk.kill_heaviest_task property 

lmkd should use ro.lmk.kill_heaviest_task property to select between
algorithms for victim selection. Set ro.lmk.kill_heaviest_task default
value to false in order to keep it compatible with previous versions
of lmkd (killing the heaviest task is a new mechanism).
