Make the hello image leaner

[NO TESTS NEEDED]

Change from using a bash script to a c file
for running the image.  With thanks to discussions
with @afbjorklund, the Containerfile was rigged
up to make the final image be only KB's in size.

Also add USER 1000 to make the image test/run as
non-root, and update the README.md
