fix(tvix): Catch errors for generator in some builtins r/7487

Nix doesn't propagate errors for the function argument to some builtins,
like genList and map:

    ❯ nix repl
    Welcome to Nix version 2.3.17. Type :? for help.

    nix-repl> (builtins.tryEval (builtins.genList (builtins.throw "a") 10)).success
    true

    nix-repl> (builtins.tryEval (builtins.map (builtins.throw "a") [ "" ])).success
    true

Note that this is untested as of this particular commit, only because a
big test suite covering all sorts of catchable error propagation issues
is coming next
