perf test: Fixes to variable expansion and stdout for diff test
...
When make_data fails its error message needs to go to stderr rather
than stdout and the stdout value is captured in a variable. Quote the
$err value so that it is always a valid input for test. This error is
commonly encountered if no sample data is gathered by the test.

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.

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.
