util-linux: restore zlib and ncurses dependencies for native

OE-Core commit 4a158b6ef125b555225472eefbe1ea226dc47c2c unintentionally
removed the dependencies for util-linux-native on zlib-native and
ncurses-native by getting append and virtclass-native overrides swapped
around; later this was tidied up to remove the append (which did not change
anything functionally). These libraries are required, so add them back in.
