Grant URI permissions to the MCS

When the PackageManagerService is asked to install from a URI, it might
be explicitly granted the permission to read from the URI content
provider. We need to pass along these permissions to the
MediaContainerService (DefaultContainerService) to ensure the MCS can
read from the content provider.
