kselftest/cgroup: fix test_stress.sh to use OUTPUT dir

[ Upstream commit 54de76c0123915e7533ce352de30a1f2d80fe81f ]

Running cgroup kselftest with O= fails to run the with_stress test due
to hardcoded ./test_core. Find test_core binary using the OUTPUT directory.

Fixes: 1a99fcc035fb ("selftests: cgroup: Run test_core under interfering stress")
