ref-manual: classes: reword to clarify that native/nativesdk options are exclusive

We explain how to create a native (nativesdk) recipe in two different
ways via a bullet list but reading quickly the instructions may mislead
one into doing both options whereas they are incompatible.

This rewords both the nativesdk and native sections so that the second
bullet point starts with an Or and explicit that this applies to target
recipes.
