Create /data/misc/stats-data/ and /data/misc/stats-service/ in statsd.rc

rather than during the runtime of statsd

The purpose of this change is to prevent causing selinux violation by
trying to mkdir to /data/misc/ directory when statsd doesn't have
permission to do so.

Bug: 71537285
Test: manually tested to make sure that there's no sepolicy violation
