[PATCH] meta-isar: Setting root password

[Alexander Smirnov <asmirnov@ilbers.de>]

This patch addresses the following issues:

1. At the moment there are two places where root password is set:
 - mulristrap scripts
 - example-raw application
So there is no need to do this twice for default Isar layout.

2. According to the README.md, the default password is 'root', so it
needs to set it back to avoid unnecessary surprise of existing users.

3. Define default passowrd as variable to have possibility to override
it from local config.
