Wrapper: don't exclude scripts, just exclude auto-recursion

When looking for the original command, previous logic excluded all
scripts - which is problematic, because gtk3-nocsd may also be used for
e.g. Python3 scripts that use Gtk3. Other programs bring their own
startup scripts that call the binary that's installed elsewhere with
certain environment variables set. Therefore, change the logic to just
anything that's symlinked to gtk3-nocsd.
