[cogl] examples: Allow installing of examples

[Robert Bragg <rbragg src gnome org>]

    examples: Allow installing of examples
    
    This namespaces all of the examples and marks them for installation
    if --enable-examples-install has been passed to ./configure. This
    simplifies packaging the examples which can be quite convenient
    for smoke testing Cogl on various platform.
