[glib/glib-2-66: 1/2] gtrace: Add G_GNUC_PRINTF annotation

[Emmanuele Bassi <ebassi src gnome org>]

    gtrace: Add G_GNUC_PRINTF annotation
    
    This allows compilers to check the format placeholders properly. It
    fixes compilation on clang, which gives a warning about untrusted
    strings being passed on to subsequent functions which require format
    placeholders.
