[gimp] plug-ins: conditional gimp_install_procedure() should be in init().

    plug-ins: conditional gimp_install_procedure() should be in init().
    
    query() is run only the first time for efficiency. Yet this plugin is
    dependent on the presence of `rawtherapee` which may be installed or
    uninstalled between GIMP startups. Therefore we should move the usual
    gimp_install_procedure() to init() so that the check is done at every
    startup instead.
