Ignore $scopeinfo in write_aiger

Browse source 
While SBY's aiger flow already removes non-assertion driving logic,
there are some uses of write_aiger outside of SBY that could end up with
$scopeinfo cells, so we explicitly ignore them.

The write_btor backend works differently and due to the way it
recursively visits cells, it would never reach isolated cells like
$scopeinfo.
