hmi-controller: fix the laucher layer width

A layer for workspace is used to display icons for invoking applications
in several pages. These pages are swapped from one to next page. The
width of the layer was decided as a size of screen before reading
weston.ini. This worked correctly because there was no feature of
clipping of layer so the width of layer was not taken account.

Now clipping feature is supported. So the width shall be set to correct
one after reading weston.ini.
