Adapt profiledef.sh when build.sh is executed

[stevleibelt]

As we can see here we are able to update the profiledef.sh file.

• adapt iso_name
• adapt iso_label
• adapt iso_publisher
• add file_permissions and add arch-config files

Have a look to the official documentation. Another example file to get some ideas is here.
