KFileItem: isWritable use KProtocolManager for remote files
When a file is not local, check if we have a protocol available for its url and that we can use it to write.
This prevents paste action to be presented in context menus of non writable protocols: remote:/ recentlyused:/
We could supplement it with a KIO::Stat call, for when the protocol supports writing.
