nfd-worker: drop deprecated command line flags

Drop the following flags that were deprecated already in v0.8.0:

-sleep-interval  (replaced by core.sleepInterval config file option)
-label-whitelist (replaced by core.labelWhiteList config file option)
-sources         (replaced by -label-sources flag)
