Ignore class_{reset|start}_post_data on non-updatable APEX.

For devices that use FDE and don't support updatable APEXes, don't
stop and restart all processes - there is no need and it only increases
boot time for these devices.

Additionally, some daemons have never been restarted in the past, and
restarting them exposes certain issues.
