refactor(@schematics/angular): use built-in POSIX path utilities for replace-nguniversal-engines migration

The use of the custom path functions from `@angular-devkit/core` have been
removed in favor of the built-in functions from Node.js. These provide
equivalent functionality with an improvement in performance. The amount
of custom code executed has also been reduced.
