Log drive touches when KOBOLD_TIMING is set

Time the two places a filter run reaches the device volume — the root
scandir and each nook book's KOReader progress sidecar — and print a
per-call line plus an at-exit total to stderr, where Alfred's debugger
shows it. Off unless the KOBOLD_TIMING environment variable is set.
