*: fix "babeld: Remove babeld from Quagga" (336724d)

This removes some more bits of babeld, particularly from:
- buildtest.sh
- redhat/ build files
- vtysh integration (which actively broke the build)

The memtype and zclient/route type are kept in place since these don't
break anything and -theoretically- make it possible to build babeld
with some Quagga integration externally.
(Keeping vtysh integration is unfortunately not as easy.)
