gnome-user-share: add recipe

- add it as runtime dependency to gnome-control-center because without it,
  the file sharing options are hidden.
- configure the paths to fit to openembedded env
- add mod_dnssd runtime dependency for apache2 as this is a requirement

To enable the feature, PACKAGECONFIG httpd needs to be added.
This is not done by default to avoid apache2 runtime dependency just by
including this recipe.
NOTE: Apache2 httpd doesn't need to be running. It'll get
      started and stopped on demand by systemd.
