haskell.packages.*.system-cxx-std-lib: make sure attr always exists

Browse source 
GHC 9.4 introduced a virtual package for linking against the C++
standard library. Since some packages depend on it when configured with
GHC 9.4 (as hackage2nix does), we need to make sure the attribute exists
or some packages will fail to evaluate. The may still build, even though
there is no shim for lower GHC versions (as far as I know).
