xmlrpc2di: configurable log level for XMLRPC calls / parameters
patch provided by A. Pogrebennyk - no build errors when using CI system

was:  082f06f5 ... and not installing default config files

Note: proper targets should be used (e.g. install-bin) if only
      binaries should be installed, or alternatively the pkg script should
      remove installed cfg files afterwards. install target
      installs the complete package
