Clean up reserved space for decompression when OTA cancelled

OTA can terminate in the following ways:

1) Before reboot, intentionally cancelled.
2) Before reboot, failed due to error
3) After reboot, failed due to error
4) After reboot, success

Cleaning up from ResetStatus should cover #1. For #2, there won't be
automatic cleanup on failure, as sometimes we resume OTA from where it
last failed. So user needs to explicitely call ResetStatus to clean up.
for #2.

Number #3 and #4 will be dealt in follow up cl.

Bug: 172911822
Test: Case #1: Intentionally cancel
  1. Allocated space:
     python3 update_device.py --allocate-only ota.zip
  2. Temp file deleted by:
     adb shell update_engine_client --reset_status
