perf script: Move filter_cpu() earlier

Generally, it should be more efficient if filter_cpu() comes before
machine__resolve() because filter_cpu() is much less code than
machine__resolve().

Example:

 $ perf record --sample-cpu -- make -C tools/perf >/dev/null

Before:

 $ perf stat -- perf script -C 0 >/dev/null
