Colin Stewart 33b6dcc976 Build/Test Tools: Add sys_get_temp_dir() to open_basedir tests.
In PHPUnit 10.3.5, 9.6.13 and 8.5.34, the child processes used for process isolation now use temporary files to communicate their result to the parent process.

This caused a failure in some tests that set the `open_basedir` PHP directive to a value that did not include `sys_get_temp_dir()`.

This adds `sys_get_temp_dir()` to the `open_basedir` value set by the tests to ensure that permission is still granted for the temporary directory.

PHPUnit uses `sys_get_temp_dir()`. To ensure the result is the same, Core's `get_temp_dir()` function is not used.
