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.

perf test: Add basic 'perf diff' test2023-12-05T18:48:52+00:00Ian Rogersirogers@google.com2023-11-20T19:04:08+00:00urn:sha1:144081ef78c36e255c08b74da86ef68e6cf0a221
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.
