viced: Log some basic fs_stateRestore stats

Browse Source 
Log how long it took to restore our fsstate.dat data, and how many
FEs/CBs we loaded. This may be of interest to anyone looking at the
impact of different relevant options (such as -fs-state-verify), and
how much callback state is being restored.

Note that we're not adding any new messages, just adding some
additional info to an existing message.
