Fix MultiSource/Benchmarks/Prolangs-C/archie-client on 32-bit systems with 64-bit time_t (#318)

Targets like RISC-V 32-bit have a 64-bit time_t. Code in procquery.c
does:
```
long now;

/* initialize data structures for this query */
(void)time(&now);
```

Which fails to compile due to passing the wrong pointer type. It works
on other platforms because commonly time_t is 32-bit on 32-bit systems
and 64-bit on 64-bit systems, so using `long` is sufficient. As the fix
is trivial and doesn't impact performance, let's fix the benchmark.
