Port QDBusAdaptorConnector meta-object to revision 6

We want to drop support for old revisions in Qt 5.

This commit brings the QDBusAdaptorConnector meta-object in sync with
current moc output.

The QtDBus implementation was assuming that the relaySlot() slot
would be created at index methodOffset() in the meta-object, but
since revision 4 that's no longer the case (signals always come
first). Made the code more robust by actually querying the
meta-object what the index is.
