Subject: [PATCH] meson: Hotfix for iconv detection on macOS

macOS/iOS do not ship iconv inside the C library, so don't try to look
for that at all when targetting macOS or iOS.

The proper fix involved changing the options and will be merged in
master: https://gitlab.gnome.org/GNOME/glib/merge_requests/759
