[glib: 1/2] gcontenttype: Add no-op versions of {get, set}_mime_dirs() on win32/macOS

[Emmanuele Bassi <ebassi src gnome org>]

    gcontenttype: Add no-op versions of {get,set}_mime_dirs() on win32/macOS
    
    These are here to prevent linker errors, since `gcontenttype.[ch]`
    aren’t compiled on Windows or macOS.
    
    The implementations are stubs to be filled out by someone who knows each
    platform, at some point in the future.

    Fixes: #1791
