cmd/go/internal/modload: only check root-promotion during tidy for lazy modules

In a lazy module, it is important that tidyRoots does not add any new
roots because the dependencies of non-roots are pruned out.

In an eager module, that property is not important (and does not hold
in general) because no dependencies are ever pruned out.

Fixes #45952
