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.
