gallery: hop presentLimitedLibraryPicker result to main queue

Browse Source 
Apple's docs say the iOS 15+ presentLimitedLibraryPicker
completion handler runs on "an arbitrary serial dispatch queue".
Flutter method-channel results must be invoked on the main queue;
calling result(nil) from a background queue produces an iOS native
crash on dismiss. Wrap with DispatchQueue.main.async.
