[meta-freescale] [oe-core PATCH v3 6/8] weston-init: Add module support for the weston-start helper

[Otavio Salvador]

To make weston-start more flexible we now support module loading. For
such modules, following functions can be used:

 - add_weston_argument
 - add_openvt_argument

Changes in v3: None
Changes in v2:
- Drop weston-lunch use as it requires PAM
