Allow building using podman

Maybe we should instead define $DOCKER in https://github.com/brave/tor_build_scripts/blob/master/env.sh so that it doesn't have to be done in each file? Also, that would allow someone to easily override.

I also note that this defaults to podman when it's installed. I'm not familiar with Podman. Is it superior to Docker? Should Brave be building with Podman?

It's a rootless implementation of Docker, someone prefers Podman, and there seems to be little difference between the two if we're just using it to build binaries.

I don't know if it would be possible to build Brave using Podman, but that would require a bit more research.

That's great!
