ui-shared: don't write <link> if favicon unset

Since the favicon setting defaults to "/favicon.ico", the user can
only unset it with favicon=. However, that would write an empty string
as the config value. Previously, such empty string always satisfied
the if condition. In this case it is better to omit the <link> entirely.
