Bill Richardson 624ee7e492 Address symlink attack on dev_debug_vboot. ...

Two things here: Use mktemp to create a unique and new temporary directory
to work in, and copy the published log file to a known path in a way that
can't be redirected with symlinks.

There are also a couple of minor tweaks to cleanup a little bit rot in the
information that the script provides.

BUG=chromium-os:8947
TEST=manual

Boot, wait 60 seconds, look for "/tmp/debug_vboot_noisy.log". It should
exist and contain useful and interesting data.
