This gives search (x) permission on the parent apex data directory /data/misc/apexdata so that directories below it may be opened. It also gives that permission on the apex data directories themselves. Bug: 147848983 Test: Build & flash, check perms are correct Change-Id: I27c4ea01602002c89d0771a144265e3879d9041a
