Tweak tests/ui/proc-macro/macro-rules-derive-cfg.rs.
- Trim some unnecessary fat from the type declaration. - Add another attribute, to make it a stronger test of `cfg_attr` processing. Note that the current output is incorrect, because it duplicates the added attribute. The next commit will fix this.
