ls: Print current duration of incomplete snapshots.

Currently the duration of incomplete (and orphaned) snapshots is shown
as 0:00. It's more interesting to see for how long the snapshot is
already being created, so print the difference of the current time
and the start time instead.

Fix an overlong line and a whitespace issue while at it.
