seq_nielsen: replace mk_fresh_var() with mk_fresh_var(sort* s) (#9037)

Browse source 
* replace mk_fresh_var() with mk_fresh_var(sort* s) in seq_nielsen; fix snode_label_html linkage

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* remove mk_var(symbol const&) from sgraph; update all callers to pass sort explicitly
