emacs: use curl to fetch trybot output, improve mac performance

By using a command to fetch trybot output, we can pipe the result
through a sed script that trims down the Mac output.  This makes
the output small enough so that compilation-mode can handle it.

While I'm at it, I can use file:/// URLs to unify more of the
"real" and "test" code paths.
