[breeze-icons] Use new suspend, hibernate and switch user icons in Breeze icon theme
Summary: This patch replaces the suspend, hibernate and switch user icons in the Breeze icon theme with the ones from system.svgz in patch D19020, so they're used throughout Plasma and not just in the sddm theme.
These icons work in Kickoff etc.
