googletest: fix build with gcc-15

* some recipes which use googletest fail with:
  gtest/src/gtest_main.cc:32: recipe-sysroot/usr/include/c++/15.0.1/ciso646:46:4: error: #warning "<ciso646> is deprecated in C++17, use <version> to detect implementation-specific macros" [-Werror=cpp]
   46 | #  warning "<ciso646> is deprecated in C++17, use <version> to detect implementation-specific macros"
      |    ^~~~~~~

  backport a fix for this.

* see https://github.com/google/googletest/issues/4701
