    build: Maintain Autotools compatibility on Darwin
    
    JSON-GLib 1.2 was the last release using Autotools on Darwin, which
    means we cannot use "1" as the compatibility version argument.
    
    We should also use the `darwin_versions` argument for `library()` to let
    Meson do the right thing depending on the platform, instead of passing
    linker flags ourselves.
    
    Original patch by: Tom Schoonjans
    
    Fixes: #41
