bus: fix pattern matching
DBus-spec defines two different pattern matchings: 1) Path and namespace prefix matching. In this case, A matches B either if both are equal, or if B is fully included in the namespace of A. In other words, A has to be a prefix of B, but end with a separator character (or the following character in B must be one). This is used for path_namespace= and arg0namespace= 2) The other pattern matching is used for arg0path= which does a two-way matching. That is, A must be a prefix of B, or B a prefix of A. Furthermore, the prefix must end with a separator. Fix the sd-bus helpers to reflect that. The 'simple_' and 'complex_' prefixes don't make any sense now, but.. eh..
