bitbake: runqueue: Drop debug statement causing performance issues

This debug statement could result in a long list of tasks which when
repeatedly sent over our IPC, slowed down the builds immensely. Remove
it in favour of other more targeted debugging added recently, bringing
back some lost performance, particularly on builds with large numbers
of tasks.
