[PATCH 2/5] tinfoil: ensure log lines get printed when tasks fail

[Paul Eggleton <paul.eggleton@linux.intel.com>]

If a task fails during build_targets(), we need to print out the log
lines as knotty does or the user will be missing information about the
failure.

(This should get some deeper refactoring, but now isn't the time for
that.)
