[perl-glib/ebassi/warnings: 2/6] Add fallback macros for deprecated sections

    Add fallback macros for deprecated sections
    
    In case we're building against GLib < 2.26, we need to provide fallback
    macros to mark sections with deprecated API use.
    
    Since versions of GLib prior to 2.26 didn't mark deprecated types,
    functions, values, or macros, we can get away with no-ops.
