Fix warnings: eval.c: call_user_func(): Out of bounds: FP.

Problem    : Out-of-bound array access @ 18429.
Diagnostic : False positive.
Rationale  : Situation is intentional. `dictitem_T` is a prefix all dict
             items whill share, but actual size of each item will be
             different depending on its key length. `di_key` array field
             is declared of size 1 just to have a field name, but real
             size will vary for each item.
Resolution : Make analyzer ignore it.
             This could be refactored to use C99-allowed variable length
             arrays, but eval.c is bound to dissappear, so no effort is
             done in that sense.
