tests: mailmap: avoid definition of unused static variables

The mailmap testdata header contains a set of static variable
definitions. As these variables aren't used in all places where they are
used, they trigger the unused-const-variable warnings. As we have
currently disabled those warnings explicitly, they are never triggered,
but we intend to enable them.

Avoid the issue by only keeping variable definitions that are actually
used in all locations. Move the others to where they are used.
