[PATCH] Fix integer truncation in systat -ifstat

[Ryan Stone]

systat -ifstat currently truncates byte counters down to 32-bit
integers.  The following fixes the issue, but I'm not very happy with
it.  u_long is what the rest of our code uses for network counters,
but that ends up meaning that our counters are 32-bits wide on 32-bit
platforms.  I could make it uint64_t but that's not very future proof.
RIght now I'm leaning towards punting on the issue and using u_long as
there is an awful lot of code that would have to be modified for
extended byte counters to actually work on all platforms.
