teams/asahi: FEX: Add xim support for GTK2/3

We're currently shipping GTK2/3 libs in the rootfs. While we're doing
that, let's also install XIM support, which actually works through X11
passthrough with muvm. This should generally make legacy GTK x86_64
apps have input method support the old-fashioned way.

Modern apps should use the Wayland input method protocol stuff, which is
already built into GTK3/GTK4 and should not require any extra shared
libraries for FEX. For muvm, that will work once we have Wayland
passthrough.
