Fix issue #2569139: Cannot login to last.fm after upgrade from Donut to FRF01B

This is a quick and dirty solution to re-assign permissions after booting
from a platform update.  It is not great, because it means that an app
can have permissions that the user didn't get to see when they originally
installed it.  Unfortunately it's not clear what else to do here, nor is
there time to do anything significant.
