fix: generate-runtime.py should ignore tcclib.h

dlclose comes from tcclib.h

generate-runtime.py with debug prints

```py for header_dir, header_reldir, header_filter, header_transform, header_kind in inputs: print(f"generate-runtime.py: header_dir={header_dir}", file=sys.stderr) print(f"generate-runtime.py: header_reldir={header_reldir}", file=sys.stderr) print(f"generate-runtime.py: header_filter={header_filter}", file=sys.stderr) for header_name, header_source in find_headers(header_dir, header_reldir, header_filter, header_transform): print(f"generate-runtime.py: header_name={header_name}", file=sys.stderr) input_identifier = "gum_cmodule_{0}".format(identifier(header_name)) for pattern in (cmodule_function_pattern, cmodule_variable_pattern): for m in pattern.finditer(header_source): name = m.group(2) symbols.append(name) print(f"generate-runtime.py: symbol={name}", file=sys.stderr) ```
