There were still three tests that shared a cache between the servers
and client that queried those servers. Give them all separate caches.

Also the error handler for debuginfod tests wasn't called when a
command inside a function failed. Since testrun is a function, there
would be no metrics or error log files listed if the testrun command
failed. Making it hard to see what went wrong. Fix this by using
set -o errtrace

Hi,

So that showed run-debuginfod-fd-prefetch-caches.sh "failed".  I
"fixed" that with the attached patch which I just committed. And also
make the cleanup and error handling slightly better (by only doing it
once).

But it doesn't really "fix" run-debuginfod-fd-prefetch-caches.sh. It
now just does nothing. The debuginfod server gets to scan a
non-existing directory and then nothing even tries to query anything
from the server. So nothing ever gets prefetched. And testing for zero
happily succeeds.

Noah, could you take a peek at this testcase and see if you can make
it do something "real"?

Thanks,

Mark
