scangobj: Do not generate unused parameters

Good point.

 {
   $TYPE_INIT_FUNC;

Unfortunately we can't do this as simple as this. Users can e.g. do

SCANGOBJ_OPTIONS=--type-init-func="gst_init(&argc,&argv)"

in the code we'll need to check if $TYPE_INIT_FUNC contains argc/argv.

Ping?

scangobj: Avoid generating unused params

The main function params may be unused depending on type init function
definition. That may lead to generating a warning about unused in a
project using gtk-doc, eg:
    DOC   Scanning header files
    DOC   Introspecting gobjects
  spice-gtk-scan.c: In function ‘main’:
  spice-gtk-scan.c:126:11: warning: unused parameter ‘argc’ [-Wunused-parameter]
   main (int argc, char *argv[])
           ^~~~
  spice-gtk-scan.c:126:23: warning: unused parameter ‘argv’ [-Wunused-parameter]
   main (int argc, char *argv[])

Check for the presence of argc and argv in the type init function
and generate main function params accordingly
