add_test: Fix version of CMake introducing CMP0158 (to 3.29)

This was missed in commit ca5a300d7f (add_test: Honor
CROSSCOMPILING_EMULATOR only when cross-compiling, 2023-11-02) when it
slipped from the 3.28 release.

@@ -25,3 +25,5 @@ This policy was introduced in CMake version 3.29. Use the
 :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
 Unlike many policies, CMake version |release| does *not* warn
 when this policy is not set and simply uses ``OLD`` behavior.
