[PATCH] oeqa/runtime/weston: Enhance weston tests

["Yeoh Ee Peng" <ee.peng.yeoh@intel.com>]

Existing weston test available make sure that a process
for weston-desktop-shell exist when image boot up.

Enhance weston tests by:
 - execute weston-info to make sure weston interface(s)
   are initialized
 - execute weston and make sure it can initialize a
   new wayland compositor

[YOCTO# 10690]
