[OE-core] [PATCH 1/3] No need to force image licence on MIT

[Geoffrey Levillain]

If there is a user-defined licence there is no need to enforce MIT
licence instead. Therefor we set MIT if there is no licence defined.

Note : It also permit to set the licence before inherit image
in overlayable images (where a licence is needed because of the files
associated to the image).
