Handle install time ephemeral permissions

Normal install time permissions can still be denied to apps that are
running as Instant Apps, properly report such permissions as not
granted.

This fix isn't the perfect fix where PermissionState handles install
time permissions and Instant Apps but that fix is more invasive and
involves a lot of code change.
