I think it's done with access-list. You must first define your access-list (either in zebra.conf or babeld.conf), so in your case something like :

access-list dont-redistribute-v4 deny any
ipv6 access-list redistribute-v6 permit any

and in your babeld.conf :

router babeld
  network eth0
  network wlan0
  distribute-list dont-redistribute-v4 out wlan0
  ipv6 distribute-list redistribute-v6 out eth0

It should work.
