perf test annotate: Use --percent-limit rather than head to reduce output
The annotate test was sped up by Thomas Richter <tmricht@linux.ibm.com> in commit 658a8805cb60 ("perf test: Speed up test case 70 annotate basic tests") by reducing the annotate output using head. This causes flakes on hybrid machines where the first event dumped may not have the samples for the test within it. Rather than reduce the output using `head` switch to `--percent-limit 10` which will stop annotate dumping functions that have an overhead of less than 10%, the noploop program should be using more. Add the missing objdump option for the pipe mode version of the objdump with a command test.
