Fix jcstress CI: create build dir before tee 
tee opens the output file immediately at startup. Since build/ doesn't
exist yet on a fresh runner, tee fails to open the file and exits with
code 1 (while still copying stdin to stdout). pipefail then picks up
that non-zero exit code, failing the step despite gradle succeeding.
