PackageCacher uses file name and modified time to determine if the
parsed cache is still valid. However, all APK-in-APEX would have
the same name and modified time. This results in the out-of-date
cache would be treated as valid.
We need to invlidate the cache for the APK-in-APEX when that APEX
is going to be installed.
