Bugfix/klish python c extension

[albmartmart]

Why I did it

When KLISH invokes Python actioners using builtin="clish_pyobj", Python C extensions (such as charset_normalizer and the SSL module) fail to load due to missing Python C API symbols. This affects all commands using this invocation method, including MCLAG commands and any new implementations.

Fixes #151

How I did it

Modified CLI/klish/patches/klish-2.1.4/plugins/clish/call_pyobj.c to load the Python shared library with RTLD_GLOBAL before initializing Python, making Python C API symbols globally available:

void pyobj_init() {  
    void *python_lib = dlopen("libpython3.11.so.1.0", RTLD_NOW | RTLD_GLOBAL);  
    if (!python_lib) {  
        fprintf(stderr, "Failed to load Python library: %s\n", dlerror());  
    }  
    Py_Initialize();  
}

I also fixed the wrong Python2 print statements from CLI/actioner/sonic_cli_mclag.py.

How to verify it

1. Build SONiC VS image with the fix
2. Login to the virtual switch
3. Run sonic-cli
4. Execute configure terminal
5. Execute no mclag domain 432 (command should work without "Internal error")

Hi @gitsabari , I saw you’ve contributed to similar issues before.
If you have a chance, could you please take a quick look and let me know if the proposed approach makes sense, or if there’s a preferred way to handle it within the project?
Thanks in advance for your time!
