OOM fixe to allow smooth RAM MNG + horrable mistake fix!

*we have auto adj code, so we must not allow any access to adj file.
*fixed init service was marked as KILL NOW! oom_score_adj = 1000 is
oom_adj = 15 highes OOM selected to be killed! this was my mistake :(
*tuned oom_kill_allocating_task to be ON with screen on and off when screen off
to save power.

now after long test OOM working GREAT! no more lags and no SODS. TNX Dorimanx!
One more error in /oom_score_adj set. FIXED.
removed unused file
