tools: Fix up 'make coverage' output by removing built stuff
agent: Move g_type_init() early in the process

This is for older GLib's, we should be running it early anyway.
ws: Pass the GDBusObjectManager to dbus_server_serve_dbus()

In later commits we'll pass an alternate implementation of
GDBusObjectManager. We make sure it has the same properties
as GDBusObjectManagerClient so that these can be used appropriately.

Initialize the GDBusObjectManager asynchronously as well.
