Arguments::create_numbered_property allocates wrong buffer in case count > 99

prop_len which is used to allocate memory is not properly calculated in case count > 99.
> size_t prop_len = strlen(prop_base_name) + strlen(prop_value) + 5;
> int ret = jio_snprintf(property, prop_len, "%s.%d=%s", prop_base_name, count, prop_value);

where 5 takes into account symbols '.', '=', '\0' and only 2 digits.

as result running java with more than 100 arguments leads to
 Error: Could not create the Java Virtual Machine.
 Error: A fatal exception has occurred. Program will exit.
