core_pp: Remove uncovered clause in is_simple_term/1

The clause for handling #c_values{} in is_simple_term/1 is never
executed. It can be safely removed, since there is a default clause
that will return 'false' in the extremly unlikely event that a

Without the clause, code such as:

  let <_v1,_v2> = <1,2>
          in {_v1,_v2}

would be printed with an extra newline:

  let <_v1,_v2> =
        <1,2>
          in {_v1,_v2}
