Don't exclude Dockerfile, Containerfiles from tar content

If the user specifies "*" in a .dockerignore or a .containerignore
then podman-remote build should not exclude the Dockerfile or
Containerfile or any content pointed to by `-f` in the context
directory.

We still need these files on the server side to complete the build.

Fixes: https://github.com/containers/podman/issues/9867
