In some environments, a variant of rpm parser is used that does not
expand Lua or shell invocations. In that environment, using
%nodejs_define_version for defining (parts of) Name:, Version:, or
Release: fields will result in them being empty or incomplete
This swaps the definition order around, so that the fields are set
first with the verbatim values.
