feat(tvix/eval): implement builtins.currentSystem r/5190
This commit implements builtins.currentSystem, by capturing the cargo environment variable `TARGET` and exposing it to rustc as `TVIX_CURRENT_SYSTEM` so it can be inserted into the source code using `env!()`. The resulting value needs to be massaged a bit, since it is an "LLVM triple". The current code should work for all the platforms for which cppnix works (thanks qyliss for generating the list!). It does *not* reject all of the triples that cppnix's configure.ac rejects -- it is much more forgiving. We can tighten this up in a future commit.
