paycheck: Allow payloads with no operations.

Due to a fix to the delta generator (CL:246670) we may actually end up
with delta payloads that contain no operations (e.g. a delta from an
image to itself). This is a good thing and we want paycheck to not rule
out trivial deltas such as these.

BUG=chromium:453659
TEST=Empty delta verification passes
