Elm.Mapbuf: do not set is_static_clip to its content

Summary:
If an object's is_static_clip is TRUE
then _evas_render_phase1_object_process does not draw the object and its smart
member from the below commit (1).

On the other hand, the Elm.Mapbuf sets is_static_clip to its content from the
below commit (2). So you cannot see the content. If the commit tried to solve
over-render, it could be changed to:

if (wd->content) evas_object_static_clip_set(wd->content, !wd->enabled);

from:

if (wd->content) evas_object_static_clip_set(wd->content, wd->enabled);

or there could be another way.

    evas phase 1 process - shortcut objects that are pure static clips only

    these objects don't actually produce - or should produce update
    regions etc. etc. as the objects that are clipped should produce those.
    they are not active objects. so skip them very early after just
    ensuring they are in delete objects if needed.

    fix over-render bug in map/mapbuf and with changed flags! that was
    nasty to find!
