cmd/go: describe dependencies in build list error messages

mvs.BuildList reports errors with a chain of modules to make it
clear why the module where the error occurred was part of the
build. This is a little confusing with "go get -u" since there are
edges in the module graph for requirements and for updates.

With this change, we now print "requires" or "updates to" between
each module version in the chain.

Updates #30661
