main: fix compilation with FEATURE_NO_XEMBED

When FEATURE_NO_XEMBED is defined then we don't support using the Xembed
interface, which will cause us to set the `VIMB_XID` envvar. With
55fb9cc (Add new env VIMB_WIN_ID to hold the gtk window id., 2021-01-25)
a related feature was added that causes us to expose the Gtk window ID
via the `VIMB_WIN_ID` environment variable. This feature also depends on
X-specific information because it uses `GDK_WINDOW_XID()` to derive the
window ID. This change thus broke Wayland-only environments.

Fix compilation by extending the `ifdef` to guard the logic that both
sets the `VIMB_XID` and the `VIMB_WIN_ID`.
