r7485: - allow test_xxx.sh to run outside of 'make test' by ensuring $PREFIX is setup
- use loopback interface only, otherwise nbtd will answer with a real
ip, which the socket wrapper code will fail to connect to
- enable eadb for posix testing
- sleeping to wait for smbd to start is pointless, as smbd won't start
till its fifo is opened due to the fifo redirection on stdin
- sleep for a few seconds to allow for nbt server to register names after opening fifo
- use bcast name resolution, so we don't rely on /etc/hosts being right
