[OE-core] [PATCH] systemd: Expose resolv-conf alternative only when resolved is built

[Alexandre Bard]

When systemd is built without internal resolver, it does not make
sense to expose it as a resolv-conf alternative and can even break
images where this alternative would be chosen, because of an
invalid symlink.
