init: Do full shutdown even for thermal shutdown
- Skipping SIGTERM / SIGKILL / umount brings race between block
device driver and fs layer. Do umount before shutting down.
- Reduce timeout to 1 sec for thermal shutdown and skip other time
taking part like fsck.
- Refactor waiting part to check time in ms so that 1 sec can
have enough resolution.
bug: 63686426
Test: adb shell setprop sys.powerctl thermal-shutdown, adb shell setprop sys.powerctl reboot and check dmesg
