glapi: glX_proto_size.py: use argparse instead of getopt 

This is roughly equivalent to the original getopt, except that it
removes the '-h' short option, which argparse reserves for
auto-generated help messages. It does retain the long option specified
by the getopt version, and changes the makefile to use that.
