bfdd: Add `show debugging [bfd]` command

This will prevent vtysh from displaying `command imcomplete`
for a `show debugging` issued and we are running this
bfd daemon.  A quick look showed me that there was not
really the ability to turn on/off debugging like other
daemons.  I imagine future work can be focused here.
