Limit Activity taskAffinity to application uid
Currently, activities with same affinity will be in the same task even
if they don't have the same uid. As a result, malicious apps may set
the same task affinity with attacked app, and hijack intents to get
permissions.
This patch limits activity task affinity to application uid. Activities
must have the same task affinity and uid to be in the same task.
