perf pmu-events: Fix testing with JEVENTS_ARCH=all
The #slots literal will return NAN when not on ARM64 which causes a perf test failure when not on an ARM64 for a JEVENTS_ARCH=all build: .. 10.4: Parsing of PMU event table metrics with fake PMUs : FAILED! .. Add an is_test boolean so that the failure can be avoided when running as a test.
