ui: format 'display-hint' output when no arguments are passed.

Browse source 
When display-hint is given format specifiers such as "~%" but no arguments,
it does not format the output, causing the specifiers to be visible in the
displayed text.

* guix/ui.scm (display-hint): Format output when no arguments are passed.
