perf test: Add basic 'perf diff' test There are some old bug reports on perf diff crashing: https://rhaas.blogspot.com/2012/06/perf-good-bad-ugly.html Happening across them I was prompted to add two very basic tests that will give some 'perf diff' coverage.

perf test shell diff: Skip test if test_loop symbol is missing in the perf binary The diff test depends on finding the symbol test_loop in perf and will fail if perf has been stripped and no debug object is available. In that case, skip the test instead.
