Fixup skinny CLI completion.

Auto complete for skinny debug allows multiple options and negation, also add 
debug all option. Usage example: 'skinny debug all -packets' (each can be 
autocompleted including -packet).

Change show device to use device name. Remove the duplicate ast_strdup's from 
place calling device complete return immediately from complete devicename and 
complete linename so that multiple options are displayed on the CLI if more 
than one option available.
