[yocto] License information for Mono recipe?

[Alex Lennon]

Hi all,

I've been doing some updating of meta-mono mono support and the license 
file has changed.

IANAL and I'd like to get this right so is anybody in a position to 
advise me on what the recipe should contain to correctly reflect the 
various licenses for mono?

Much appreciated,

Alex
