[clutter] Rework debug output

[Emmanuele Bassi <ebassi src gnome org>]

commit 59f395d856e46f6c6a2bc8901db3ecb3f73ee50a
Author: Emmanuele Bassi <ebassi linux intel com>
Date:   Tue Nov 15 17:39:49 2011 +0000

    Rework debug output
    
    Make it consistent across the various build options (with or without
    profiling enabled), and add a timestamp using the monotonic clock to
    every debug message.
