gtimelog: add adwaita-icon-theme to dependencies

[goetzk (Karl Goetz)]

When running without adwaita-icon-theme there are errors on load and any time a button is hovered over. The places where icons should be are generic boxes.

After installing adwaita-icon-theme, the errors are gone and the UI has buttons in the correct places.
