t4203: demonstrate loss of uppercase characters in canonical email

The email addresses read from .mailmap are downcased before being
inserted into the mailmap data structure, which undesirably loses
information.  It is impossible, for instance, to map <first.last@host>
to <First.Last@host>. Demonstrate this problem.
