Unit tests: Use Md5sum to decide whether to discard MMAPs

Previously, we used the array index of the test files, and discarded
MMAPs for even-indexed files.

This became a problem when we wanted to insert new files into the list
of test files as the following files would get shifted by one. To make
this more robust, use Md5sum prefixes instead of array indexes to
decide. This should yield a 50/50 mix of discard vs no-discard and is
immune to adding or removing files.
