Actually, on NetBSD 5.0, there is a /proc file system, like on FreeBSD.
Let's extend get_rusage_as() accordingly. In practice it makes no
difference, though, since iterating over /proc/curproc/maps yields the
same value as the setrlimit based approach.

        get-rusage-as: Improve on NetBSD.
        * lib/get-rusage-as.c (get_rusage_as_via_iterator): On NetBSD, use
        /proc, like on FreeBSD.
