include python-gdb.py in base containers

This file is relatively small, but helps a lot while debugging with gdb. Even if it is compressed, it would help a lot!

It is in /usr/src/python before it gets wiped. Will you accept a PR if I submit one?

Sorry for the delay! If there's a simple way we can help enable gdb usage, I'm definitely +1!

Does gdb's "auto-load-safe-path" have a default value we could take advantage of?

Any updates on this?

Still blocked on figuring out how we can enable it safely/reliably -- if you've got something working, sharing it would be helpful. 😅
