Florian Mayer 7ad383f181 Expose filesystem read events in SELinux policy.
Without this, we only have visibility into writes.

Looking at traces, we realised for many of the files we care about (.dex, .apk)
most filesystem events are actually reads.

See aosp/661782 for matching filesystem permission change.
