Subject: [PATCH] [CocoaPod] Properly quote path to libsignal_ffi.a in build
 script

Also, if the library somehow isn't built when used as a non-local
CocoaPods dependency, don't suggest running swift/build_ffi.sh;
CocoaPods will have removed it already. Re-running `pod install` is
more likely to help, though in practice something's probably gone
wrong in the configuration.
