Add PolyKinds extension to Data.Monoid
Summary:
Carl Howells pointed out[0] that the `Monoid` instance for
`Data.Proxy.Proxy` is only defined for types with kind *.
This is a very mild change. Furthermore, Edward Kmett revealed[1] that
it was supposed to be there all along -- the extension simply got lost
in commit 1d1ff77aaa09efaddc8cfe0dcf92d6763297cf11, as pointed out by
Adam Vogt[2]. This used to be correct in GHC 7.6, so this commit fixes a
regression.
This addresses #9317.
