examples/ipsec-secgw: move global array from header

When STATS_INTERVAL is set to a non-zero value the
core_statistics array will be defined in multiple
compilation units and this can trigger a linker error
on particular environments. In order to fix this the
core_statistics definition was moved out of the header file.
