Subject: [PATCH] autotest: create the temp dir in $TEMP

on modern systems, this makes it likely to end up on tmpfs, which is a
lot faster and ssd-friendlier.

the symlink is not deleted at the end, to minimize fs churn. that means
it will be dangling after a reboot, which gets fixed in the next run.
