[2.0-devel 2/2] Adapt the tests to the fact that we are now rounding up by default

[dashea]

From: Vratislav Podzimek

The change was enforced by the fact that the libbytesize author (me) has always
found ROUND_HALF_UP confusing which is why libbytesize doesn't support
ROUND_HALF_UP. The default is now ROUND_UP, but we are specifying it explicitly
everywhere in our code anyway.
