update_verifier is being passed the current stage of Full Disk
Encryption (FDE): "nonencrypted" or "${vold.decrypt}". However, since
FDE is no longer supported, it's actually now always "nonencrypted"
(which is confusing because there *is* encryption, it's just not FDE).
Also, update_verifier doesn't actually do anything with this
command-line argument, and based on the git history it never has.
Therefore, let's update the service definition to just have an
"update_verifier" service that passes no command-line argument.

update_verifier should be in the cache group, not 'class'.
Also use PLOG instead of LOG if care_map.txt cannot be opened.

Highest ioprio is 0 for CFQ and we should run update_verifier with that.
Tested on device and showing boottime decreased.

Raise the priority and ioprio of update_verifier and launch with
exec_start. This saves ~100ms of time before `class_start main` is executed.
