[glib/wip/smcv/gdbus-server-auth-test] gdbus-server-auth test: Include gcredentialsprivate.h

[Simon McVittie <smcv src gnome org>]

commit 29f505444a260c789423d4996233bc5db79d9d45
Author: Simon McVittie <smcv collabora com>
Date:   Mon Nov 4 10:21:51 2019 +0000

    gdbus-server-auth test: Include gcredentialsprivate.h
    
    Otherwise we'll never test the EXTERNAL-only mode, because that relies
    on testing the private macros
    G_CREDENTIALS_UNIX_CREDENTIALS_MESSAGE_SUPPORTED and
    G_CREDENTIALS_SOCKET_GET_CREDENTIALS_SUPPORTED.
    
    Fixes: 9f962ebe "Add a test for GDBusServer authentication"
