update: allow preserving temp directory

If you're diagnosing problems with the bitbake server when running the
update script, then you need to be able to look at
bitbake-cookerdaemon.log, but you couldn't do that after the fact
because the temporary directory it gets written out to was being
unconditionally deleted. Add a --keep-temp option which preserves it and
some debug messages to tell you where it is.
