cad/ngspice_rework: fix build with libc++ 21
With libc++ 21 cad/ngspice_rework fails to build, with errors similar to:
In file included from hicumL2temp.cpp:11:
../../../../src/include/cppduals/duals/dual:444:8: error: 'is_compound' cannot be specialized: Users are not allowed to specialize this standard library entity [-Winvalid-specialization]
444 | struct is_compound<duals::dual<T>> : true_type {};
| ^
/usr/include/c++/v1/__type_traits/is_compound.h:25:8: note: marked '_Clang::no_specializations' here
25 | struct _LIBCPP_NO_SPECIALIZATIONS is_compound : _BoolConstant<__is_compound(_Tp)> {};
| ^
/usr/include/c++/v1/__config:1167:9: note: expanded from macro '_LIBCPP_NO_SPECIALIZATIONS'
1167 | [[_Clang::__no_specializations__("Users are not allowed to specialize this standard library entity")]]
| ^
This is because libc++ 21 no longer allows specializing a number of
standard library entities. Delete out the specialization to make the
build complete.
