[RFC PATCH v2 3/7] app/test-fib: fix size of the tables for large counts

[Vladimir Medvedkin]

The sizes of the routes and lookup tables are computed in 32 bits, so
more than 268M IPv6 addresses for lookup overflow the size passed to
rte_malloc() and the tables are written past their end.

Widen the multiplications to size_t.
