dbg:fun2ms: allow empty list as head
Running 'dbg:fun2ms(fun([]) -> return_trace() end' resulted in an error "dbg:fun2ms requires fun with single variable or list parameter" But the empty list is actually a list and it is a valid value as a match-spec head (matching on arity-0 functions). Although its practical use is questionable this commit eliminates a small limitation of ms_transform which is not present in the match-spec grammar.
