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

[Simon McVittie <smcv src gnome org>]

commit fdcfb9c22030e9bbb4297ec1f206901d963ccbf6

    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.
    
    This results in the 'out' label becoming unused on platforms like Linux
    where EXTERNAL authentication is supported, so #ifdef it appropriately.
    
    Fixes: 9f962ebe "Add a test for GDBusServer authentication"
