MapboxNavigation podspec fails validation

[1ec5]

MapboxNavigation.podspec fails CocoaPods validation due to some warnings. (I have to pass --allow-warnings every time I push the podspec to trunk.) Some of these warnings are upstream in AWSCore and Pulley. The warnings in MGLMapView+MGLNavigationAdditions.h are caused by the hack in #57. Until mapbox/mapbox-gl-native#6867 is fixed, we should silence the warning using #pragma clang compiler directives.

[!] The spec did not pass validation, due to 6 warnings (but you can use `--allow-warnings` to ignore them).

Let’s keep this open to track reporting and fixing the upstream warnings, since they block pushing to CocoaPods trunk without the special flag.

This issue is long out of date: we removed the AWS SDK and Polly dependencies in #617 and the Polly dependency in #785.
