ss: policy: atoll needed for 32-bit machines

On 32-bit Linux compilers, long int == int == 32-bit.  So even atol() cannot
handle ints above 0x7fffffff and clips any it finds at that.

There's only one instance in policy-json.c, use atoll() cast to uint64_t
to allow values up to 64-bit INT_MAX even on 32-bit machines.
