yb_build.sh was calling ensure_test_tmp_dir_is_set() before launching ctest, which exported TEST_TMPDIR with yb_build.sh's own PID into the environment. All parallel run-test.sh processes spawned by ctest inherited this value and skipped creating their own unique directories, causing them to clobber each other's temp files mid-test. The call is unnecessary since run-test.sh calls ensure_test_tmp_dir_is_set() itself, creating a unique directory per process.
