Since gtk_im_multicontext_get_context_id returns wayland, we don't recognize what IME on GTK.  log is coming.

Sounds like that Wayland should fix it. On the other hand, we should refer XMODIFIERS when it returns "wayland"?

Attachment: Bug 1508302 - Make IMContextWrapper::GetIMEName() refer XMODIFIERS env when gtk_im_multicontext_get_context_id() returns "wayland"

On Wayland, gtk_im_multicontext_get_context_id() returns
"wayland". However, we need to know actual IM which works
behind Wayland. Fortunately, XMODIFIERS env includes IME
name like "xim" case. Therefore, we can refer it instead.
