shadow: use update-alternatives to handle groups.1

This patch fixes the following error at do_rootfs:

  update-alternatives: Error: not linking /PATH/TO/rootfs/usr/share
  /man/man1/groups.1 to /usr/share/man/man1/groups.1.coreutils since
  /PATH/TO/rootfs/usr/share/man/man1/groups.1 exists and is not a link

The problem can be reproduced by adding the following lines to local.conf
and then building an image:

  EXTRA_IMAGE_FEATURES:append = " doc-pkgs"
  IMAGE_INSTALL:append = " shadow coreutils"

groups.1 is handled by update-alternatives in coreutils recipe, so
do it in shadow recipe too.
