fix(tvix/eval): gently attempt to create state dir r/4547
If the directory in which REPL history is stored does not exist,
gently try to create it, but do not raise an error if it doesn't work.

We may want to warn about it, but in general this sort of
non-essential feature should not cause a hard failure.
