Preserve interrupted state across waiting for future

A normal synchronous binder call would not be influenced by an
interrupted thread. With the move to asynchronous keystore IPC we wait
on a future which can throw an interrupted exception. The Java crypto
API does not expect the implementation to throw interrupted exceptions
though. So to preserve the expected behavior we wrap the Future.get()
calls in a loop that handles the interrupted exception and sets the
interrupted state after the get completed successfully.
