Revert "init: make reboot_on_failure not apply to manually stopped services"
This reverts commit 1c51525f6686a97e32c166facad93fc97eacf0f9 because it
accidentally made reboot_on_failure be a no-op for all services. This
is because Reap() itself calls KillProcessGroup() on devices with a
vendor level >= R, which in turn sets SVC_STOPPING. I had overlooked
this somehow, probably because I didn't consider that a service can
consist of multiple processes.
It turns out that real FDE devices don't actually need the above commit
because FDE devices aren't allowed to have updatable apexes enabled, and
without updatable apexes enabled, apexd exits automatically and
therefore doesn't have to be stopped. This can be verified by using the
aosp_cf_x86_phone_noapex build target, rather than aosp_cf_x86_phone
which I had used for testing before. So just revert it for now.

CLD_EXITED or an status other than '0', reboot the system with the target specified in
_target_. _target_ takes the same format as the parameter to sys.powerctl. This is particularly
intended to be used with the `exec_start` builtin for any must-have checks during boot.
- A service being stopped by init (e.g. using the `stop` or `class_reset` commands) is not
- considered a failure for the purpose of this setting.
