[Vm-dev] Update Pharo VM License

[Ron Teitelbaum]

Hi Igor,  

Hope you are doing well!

Yes that's the one.  The file
https://github.com/pharo-project/pharo-vm/blob/master/LICENSE should be
updated to match
http://www.squeakvm.org/cgi-bin/viewvc.cgi/squeak/branches/Cog/LICENSE?revis
ion=2669 

all the best,

Ron Teitelbaum
