Subject: [PATCH] Fix evaluation of packages.default not using mkDerivation

The mock pkgs set passed `{}` as the value for unknown args; if a
package def tried to evaluate one, this can raise an error that can't be
caught. Replacing the default value with `throw ""` enables bailing out
if one of the fake args is accessed.
