[Test] Ignore test infrastucture sources in debugging tests

This solves no immediate deficiency, but is a to-do that arose as part
of an ongoing effort to port the old, slightly too restrictive
checkLocalVariableTable tests to the more "functional" debugger
infrastructure.

This just shaves a little bit of overhead off the test expectations
and couples them less tightly to the specifics of the test
infrastructure.
