fix(cordova): Update build output path

[MaximBelov]

Instead of build/emulator, we'll have build/Debug-iphonesimulator and instead of build/device, we'll have build/Release-iphoneos.

@sean-perkins @liamdebeasi @mhartington @jcesarmobile can we please merge this fix already? it's been over a year since the issue appeared with the release of cordova ios 7.0.0

EDIT: it seems that there's already an open pull request and better, as it verifies the cordova version https://github.com/ionic-team/ionic-cli/pull/5065
