Staged files should be deleted from /data/staging once installation
is complete, regardless of failure or success. If a session fails
pre-reboot verification, then it can be deleted before reboot.
Bug: 123624108
Test: manual testing
- create two apex files; aosp signed and dev signed
- flash device with internal master
- aosp signed apex file will fail pre-reboot verification
- check that files are deleted in /data/staging
- repeat with multiple package
- dev signed package passes pre-reboot verification
- on reboot, files should be deleted from /data/staging
