add ppc64le to Architectures, support sudo in container

[eddelbuettel]

This addresses rocker-org/rocker#409 requesting ppc64le support by adding, and updates the Dockerfile by one commit adding sudo support which is useful if one launches container with -u 1000:1000 as I now do more often :)

We usually recommend against adding sudo to official-images, since the same can be accomplished more securely with docker exec --user 0:0 -it ....

[eddelbuettel]

I was wondering if there was a policy. In that case I will revert.

[eddelbuettel]

I force-pushed an update removing sudo, leaving the other two changes.
