xenballoond.init: remove 4 from default runlevel

Remove 4 from default runlevel in xenballoond.init.

Similar to what changeset 24847:0900b1c905f1 does in xencommons, remove
runlevel 4 from the other runlevel scripts. LSB defines runlevel 4 as
reserved for local use, the local sysadmin is responsible for symlink
creation in rc4.d.
