Update ProcessRecord ApplicationInfo for RROs

When overlays update, the changes in ApplicationInfo are propagated
to affected processes. The ApplicationInfo in the ProcessRecords of the
running processes are not updated in ActivityManagerService. Persistent
processes reuse the existing ProcessRecord when they are restarted, so
they are restarted with outdated overlay paths.

This change updates the ApplicationInfo of ProcessRecords when overlay
paths change.
