fix(ngcc): make the build-marker error more clear (#32712) 

The previous message was confusing as it could be
interpreted as only deleting the package mentioned.

Now we compute and display the actual node_modules
path to remove.

See https://github.com/angular/angular/issues/31354#issuecomment-532080537
