[gtksourceview] Avoid type redefinitions

[Sébastien Wilmet <swilmet src gnome org>]

commit 42ffea75552f30a44a35ba70c3d8c177e5319656
Author: Sébastien Wilmet <swilmet gnome org>
Date:   Wed May 17 17:19:11 2017 +0200

    Avoid type redefinitions
    
    The G_DECLARE_* macros already define the types. Support for type
    redefinition requires C11, but we don't want GtkSourceView to require
    C11 yet.
