[PATCH weston 3/4] ivi-shell: fix layout_layer.view_list is not initilized per a screen.

[Nobuhiko Tanibata]

From: Nobuhiko Tanibata <NOBUHIKO_TANIBATA at xddp.denso.co.jp>

This is potential bug when it supports several screens. If view_list is
initilized here, the views, which are set by the previous screen, are
cleared. So View list shall be initilized in front of wl_list_for_each
of all screens.
