Adjustment needed for performance tests in wrt-commons

Adjustment needed for performance tests in wrt-commons

The change "Add summary view to all security tests" colids with DPL
performance test in wrt-commons (commit: Add RUNNER_PERF_TEST_BEGIN()
and RUNNER_PERF_TEST_END() macros for performance tests). Without
this patch a build-break in security-test will occur after applying
performance tests feature to wrt-commons repository.
This patch fix the build break - security-tests can be build with
and without performance test in wrt-commons.

Verify:
    Build wrt-commons with patch "Add RUNNER_PERF_TEST_BEGIN()
and RUNNER_PERF_TEST_END() macros for performance tests". Then build
security-tests. Run all tests - there should be no changes in test
results.
