app launchers should NOT modify /proc/sys/vm

Currently, the navit (routing app) launcher script modifies
/proc/sys/vm/overcommit_memory without ever setting it back. This change
should -if at all- should only be done with serious evaluation on the
respective devices IMHO. I don't want to introduce random OOM process
killings because apps start using the RAM the kernel has promised to them.

Do I get the OK to remove the relevant lines? I will follow up on this
mail with a patch that you can ACK.
