4971 - clean up a few scripts

Some of them are no longer useful; drop them.

For the rest, have useful usage messages. And also be a little more principled
in where we introduce CFLAGS, and where we expect it to come in from the
commandline.

I'm choosing not to call gen/run/dgen/drun from test_layers because it
makes test_layers harder for newcomers to read. The scripts aren't the
first thing people should see, they're just useful once you're up and running
hacking on SubX.
