Dockerfile.isar: support of sbuild

Browse Source 
Upcoming support of sbuild in Isar requires some additional tools
to be preinstalled.

Also, `builder` user should be in `sbuild` group.

Additionally, to use external volume for schroot overlay because
the 'upper' overlayfs layer of sbuild can't be based on another
overlayfs filesystem that happens in case of using Docker.
