Do not repeat verbose/debug mode handling

Scripts are supposed to be launched as sub-commands of /bin/saturnin, which
can easily handle this for them.

Or you can still set these variables by hand.  (i.e. `FFOO_DEBUG=true saturnin-www`)

-    --)             shift; break                ;;
-    *)              break;                      ;;
