    locate: Accept ‘--clear’ without additional arguments.
    
    Fixes a bug whereby ‘guix locate --clear’ would end with the “no files
    to search for” error.
    
    Fixes <https://issues.guix.gnu.org/66799>.
    
    * guix/scripts/locate.scm (guix-locate): Do not emit “no files to search
    for” error when 'clear? is set in OPTS.
    * tests/guix-locate.sh: Test it.
