stat+vty: fix printing of rate counter values

When creating the mgcp statistics (DLCX) and also when printing
values in the VTY. The printf placeholder %lu is used. However,
this is not portable when the same code is compiled on a machine
with different integer size (e.g. armv7).

- Use PRIu64 when printing ->current value of the rate counters
