Joachim Wiberg a7e81f45c6 test: slay must cache oldpid to an instance specific ramdisk
Running tests in massive parallel causes failing startk-kill-service.sh.
This in turn was caused by the shared test tool 'slay' that cached its
"oldpid" file to a shared area of the rootfs (tenv-root).  It must use a
test instance-specific ramdisk.
