fix(@angular/cli): Align tsconfig output dir to out-tsc. Add out-tsc to .gitignore

Added /out-tsc to the .gitignore blueprint. If someone runs tsc -p src/tsconfig.spec.json it outputs to the ../out-tsc folder. These should
be ignored.

Also changed
https://github.com/angular/angular-cli/blob/master/packages/%40angular/cli/blueprints/ng/files/e2e/tsconfig.e2e.json#L13 to ../out-tsc/e2e so that they all match.
