Copy of license file from parent folder in sdist doesn't work

[NiklasRosenstein]

In a mono repository, a package can inherit the license file of the repo by temporarily copying it into the package folder during setup.py. This doesn't work anymore. Looking at databind.core==1.1.3's setup.py, I can see

_tempcopy('../../LICENSE.txt', 'LICENSE.txt')

I belive that is one ../ too many.

Running shut mono update causes the bad path, but shut pkg update fixes it.
