gtk-doc: inherit classes only if gtk-doc is enabled

Respect GTKDOC_ENABLED when inheriting python3native and DEPENDing on
qemu-native, as they're not needed when disabled.

python3native is required as otherwise the host Python is most likely used which
may or may not have python3-six installed (a requirement of gtk-doc).
