Increase the level of depth of apk paths

We are updating apps' apk path to have a two-level structure.

Default apk path of an installed app:
Before: /data/app/[packageName]-[randomString]/base.apk
After: /data/app/[randomStringA]/[packageName]-[randomStringB]/base.apk

This CL increases the valid level of depth for apk paths.
