[CRIU] [PATCH 2/2] zdtm: Add maps02 test

[Cyrill Gorcunov]

In a sake of nonlinear mapping.

Still the test is out of normal test-flow
since it's "always fail" case (because we
don't support nonlinear mapping yet, but
this test code might be needed in future.
After all I've been using it for testing
proc-parsing procesure).
