Fixed unused attribute compilation error for GCC 13 (#17188)

With `decltype(&pclose) ` for the destructor type of the `unique_ptr`, gcc makes the signature inherit the attributes of `pclose`. The compiler then ignores this attribute as it doesn't apply within the context with a warning, and since we have `-Werror` on for ignored attributes,  the build fails.
This happens on gcc 13.2.0.
