gnome-control-center reads this data from
/usr/share/X11/xkb/rules/evdev.xml, from the xkb-data package.  If you
have org.gnome.desktop.input-sources.show-all-sources set, it will also
read from evdev.extras.xml.  Between jessie and stretch, Malayalam has
moved from evdev.xml to evdev.extras.xml.  So you can get it to show up
with this command:

    dconf write /org/gnome/desktop/input-sources/show-all-sources true

I have no idea why it's been moved to evdev.extras
