Only write snapshotctl_log_data_file for userdebug_or_eng.
Test: boot, still see log

When snapshotctl merge is called on sys.boot_completed
and /metadata/ota/state does not exist, it now tries
to initialize it by creating one.
Test: no selinux denials on boot

snapshotctl is a shell interface for libsnapshot. After rebooting
into an updated build, on sys.boot_completed, init calls
snapshotctl to merge snapshots. In order to do that, it needs to:
- Talk to gsid to mount and unmount COW images
- read the current slot suffix to do checks (and avoid merging
snapshots when it shouldn't).
- read / write OTA metadata files to understand states of
the snapshot
- delete OTA metadata files once a snapshot is merged
- collapse the snapshot device-mapper targets into a plain
dm-linear target by re-mapping devices on device-mapper
Test: reboot after OTA, see merge completed without denials
