kyber-server: offer to set up kyber-launcher at end of install

If the kyber bin symlink and desktop entry are not present, prompt to
set up the launcher. Calls install_kyber_launcher directly if already
loaded (wizard), or sources kyber-launcher.sh when run standalone.
Skips the prompt on rerun if the launcher is already installed.
