test: use bundle2 for exchange in test-largefile

Using bundle2 for exchange unlock the usage of changegroup version 2. This
version of the changegroup held more information (delta base) that result in a
small increase in content size.

It also lead to reordering of output because the exchange scheduling is a bit
different.
