Update builder images to include libsodium
Currently there is an open MR to add support for encrypting token secrets to Keysmith, built on top of libsodium: https://invent.kde.org/kde/keysmith/-/merge_requests/33 Once that MR (or something like it) is merged in, Keysmith builds will start to depend on libsodium. This MR provides the necessary updates to Jenkins builder images (SUSE).
