nixos-option: fix #47722 when missing ~/.nix-defexpr/channels
The problem was that the non-fatal warning was not omitted
from the output when constructing a nix expression.
Now it seems OK for me.  When return code is OK,
the warnings don't get passed anywhere, but I expect
that won't matter for this utility.  Fatal errors are still shown.
