packagegroup-core-lsb/-full-cmdline: add bzip2

We are having the following error when using 'tar' from tar
recipe to decompress .tar.bz2 files.

  tar (child): bzip2: Cannot exec: No such file or directory
  tar (child): Error is not recoverable: exiting now
  tar: Child returned status 2
  tar: Error is not recoverable: exiting now

The tar package is introduced by these two packagegroups into image.

>From the README file from tar's source codes:

  """
  ** gzip and bzip2.

  GNU tar uses the gzip and bzip2 programs to read and write compressed
  archives.  If you don't have these programs already, you need to
  install them.
  """

So we'd better cluster gzip and bzip2 with tar. These two packagegroups
already get 'gzip', so we also add 'bzip2'.
