cpp,tests: Launch dirmngr with gpg-conf

* lang/cpp/tests/run-wkdlookup.cpp (main): Replace backslashes with
forward slashes in homedir returned by GpgME::dirInfo. Use "gpgconf
--launch dirmngr" to start dirmngr.
--

With this change the same code as by QGpgMEWKDLookupJob is again used to
launch dirmngr. It also fixes the bad example of starting dirmngr
without the help of gpgconf.
