samba-tool domain backup currently crashes when it tries to backup a symlink to a non-existent file.
With these two patches, we first make it not crash, then make it not try to follow the symlink at all.
The second patch will change the behaviour when Samba directories contain symlinks to real files: they will now not be included (symlinks to directories were never followed).
