swift: fix build w/glibc-2.31

Browse source 
https://hydra.nixos.org/build/123279517

Internally used `compiler-rt` had to be fixed for `glibc-2.31`,
basically the same approach as in the LLVM fix
(7137183bbe05738246be2be0e704c1be9bf19947).

As soon as a newer `compiler-rt` is used for `swift`, this patch can be
removed again.
