bash-completion: look for look completions

The look(1) uses positional arguments, where first one is a word from
dictionary.  It is reasonable to assume most of the time people search from
system word lists so propose completions from there.  The second argument is
a dictionary file, that might invalidate the first input but that only
happens to users who have an idea what the want without bash-completion.
