[at-spi2-core] Ensure that X11 symbols are only used when necessary

[Mike Gorse <mgorse src gnome org>]

commit 0f3d979dc297790d8a98fab734d45751bf4fec85
Author: Emmanuele Bassi <ebassi gnome org>
Date:   Fri Nov 18 11:03:36 2016 +0000

    Ensure that X11 symbols are only used when necessary
    
    Since at-spi2-core can be build with X11 support disabled, we need to
    ensure that we include and build the X11-specific bits only when needed.
