new-for-builtins & no-new-buffer: Handle line breaks after new keyword

[fisker]

When class name is not on the same line with return, auto-fix can break code.

() => {
	return new //
		Buffer()
}

() => {
	return // returns `undefined` here
		Buffer.from()
}

Added parentheses after return to fix this.

Can you fix the merge conflict?
