cc-wrapper: deunify clang/gcc treatment of -isystem
In https://github.com/NixOS/nixpkgs/pull/209870 I tried to unify the
treatment of clang and gcc in cc-wrapper as much as possible.
However it appears that I went too far.
Clang requires -isystem flags in order to be able to find gcc's
libstdc++. Gcc does not need these flags. If they are added,
gfortran will get confused:
https://github.com/NixOS/nixpkgs/pull/209870#issuecomment-1500550903
This commit deunifies the chunk of code that adds the -isystem
flags, and explains why this chunk applies only to clang.
