libfm does not build without gio/gdesktopappinfo.h

[jtojnar]

We started building glib with Cocoa on MacOS, which makes it not build gio/gdesktopappinfo.h header:

https://gitlab.gnome.org/GNOME/glib/blob/be10f19752223f2607ba1fe00408c75920792aba/gio/meson.build#L412-429

Unfortunately, this also broke libfm, which depends on the header:

  CC       base/libfm_la-fm-app-info.lo

Since you use autotools, perhaps you need to do the same thing glibmm does:
