perf test: Add system-wide mode in 'perf record' tests
Add system wide recording test with the same pattern. It'd skip the
test when it fails to run 'perf record'.
For system-wide mode, it needs to avoid build-id collection and
synthesis because the test only cares about the test program and kernel
would generate the necessary events as the process starts.
