providers/runqueue/taskdata: Optimise logger.debug calls

A run of "bitbake bash -c unpack" when the task has already been
completed resulted in about 9000 calls to logger.debug(). With this
patch which comments out some noisy/less usefull logging and moves
other logging calls outside loops, this number is reduced to 1000
calls. This results in cleaner logs and gives a small but
measurable 0.15s speedup. The log size dropped from 900kb to 160kb.
