Fix integer sizing issues in the NetworkIO Meter

On Linux kernels the size of the values exported for network
device bytes and packets has used a 64 bit integer for quite
some time (2.6+ IIRC).  Make the procfs value extraction use
correct types and change internal types used to rate convert
these counters (within the NetworkIO Meter) 64 bit integers,
where appropriate.
