Log:
  lualoader: Always return a proper dictionary for blacklist
  
  If module_blacklist isn't specified, we have an empty blacklist; effectively
  the same as if module_blacklist="" were specified in loader.conf(5).
  
  This was reported when switching to a BE that predated the module_blacklist
  introduction, but the problem is valid all the same and likely to be tripped
  over in other scenarios.
