toaster: Avoid unnecessary local to local copy of cooker log

The cooker log is copied from its original (bitbake) location
to an artifact directory chosen by the user (chosen when
checksettings.py runs as part of the managed mode;
it's one of the annoying questions you're asked at startup).
The copy happens as part of the runbuilds script run, which
is started in a loop from the toaster startup script
in managed mode.

When a user requests the log for a build via toaster, they
are getting the log which has been copied to the artifact
directory, not the original bitbake log.

This works for the managed case, where the runbuilds command is
running in a loop and copying log files for completed builds to
the artifact directory. However, in analysis mode, there are two
problems:

1. checksettings isn't run, so the artifacts directory isn't
set. toaster is then unable to figure out where the log files
should have been copied to.

2. The log files aren't copied to the artifacts directory
anyway, as runbuilds isn't running in analysis mode.

To fix this, just point the user to the local bitbake log file
in its original location. This avoids the copy step, and means
we can remove a whole question from the toaster startup sequence,
as we no longer need an artifact directory.

The only downside to this is that it's not appropriate for
remote bitbake servers. We will need to revisit this and
possibly reinstate the copy step once we have to reconcile
local and remote builds and make their logs available in
the same way.
