Fix these -Wconversion warnings in the foreign benchmarks:

In this case the issue is that we're converting from a signed type to an
unsigned type. So, if the source value is negative, it will be positive after
conversion.
Since the source value is a Java array length in both cases, the value can not
be negative, so we simply fix this by casting to `size_t` explicitly.
