Evas textblock: Fix it->x value during layout

This updates it->x when visiting each item in the line layout code,
as it was always 0, even when it was used during item rollback.
Fortunately, in the above case a 0 value was actually expected, so
this does not actually affect current behavior.

This fix is mainly for consistency and future development.
