Preserve device specific keys in Info.plist

Browse Source 
Apple's Info.plist support platform and device specific keys to augment existing
keys. For example `UISupportedInterfaceOrientations~ipad` replaces
`UISupportedInterfaceOrientations` when running on an iPad.

By using Bundle.infoDictionary, Apple will pre-process the Info.plist and replace
any key with its device specific variant. Since AltStore does not support iPad,
this will strip out any iPad specific keys for the installing app.

We add an extension Bundle.completeInfoDictionary that will return the original
de-serialized dictionary including all the device specific keys.
