data: Lower down gnome-shell process' OOM score

Browse source 
When GNOME shell runs on a less memory system (for example 3 GB RAM), it
is usually killed by the kernel OOM-killer easily. Because, it has a
higher OOM score. However, GNOME desktop environment cannot do anything
when the GNOME shell is killed.

This commit adjusts and lowers down gnome-shell process' OOM score to
avoid being killed by the kernel OOM-killer too early. In other words,
sacrifices other processes first.
