expand_new_virtuals: save atom unevaluated use

This leads to a better unsatisfied USE message than the one reported
in bug 353933, comment #3. TODO: Fix it so that these generated
atoms don't break depgraph._get_dep_chain(), due to not being
identical to the original atoms and therefore breaking
extract_affecting_use().
