haiku package info: declare a few provided commands

sh, awk, wget, etc. are currently provided by haiku.hpkg. Declare
them accordingly, since they are already referenced by some
HaikuPorts packates. For the generic ones ("sh", "awk") I've used
version 0.0.0 for the time being; we may need to reconsider that.
