Optionally ignore null-valued derivation attributes
This allows adding attributes like
attr = if stdenv.system == "bla" then something else null;
without changing the resulting derivation on non-<bla> platforms.
We once considered adding a special "ignore" value for this purpose,
but using null seems more elegant.
