Subject: [PATCH] [unittest] Use TempDir() in gtest death-test stream capture
 on Linux

gtest's CapturedStream on Linux hardcoded /tmp/ for its temp file
without consulting the environment, causing failures in sandboxed
environments where /tmp is read-only. Use TempDir() instead, which
checks TEST_TMPDIR then TMPDIR and falls back to /tmp/, matching the
behavior already present on Android and macOS/iOS.
