[glib] Fix build with -Werror=format

[Matthias Clasen <matthiasc src gnome org>]

commit 9e9d028b96b3e19902a40b930418a0ec3e30ccfc

    Fix build with -Werror=format
    
    There were a few places in gmarkup.c where we were giving
    pointer differences when integers are expected. Fix that
    by explicitly casting to int.
