fix last modified time
For cluster packages [i.e. packages that are split among multiple APKs]
the codePath is the directory containing the APKs. This normally works
well since the directory is created newly on update. However, it breaks
down during OTA when the directory modification time may or may not
change.
Specifically for cluster packages, we determine the packages "last
modified time" as the date of the newwest APK added to the package.
