Reexport GHC.Integer.Logarithms from base

[Bas van Dijk]

+1

This would make packages like integer-logarithms and scientific simpler to
define since they don't need to add conditional compilation to support
integer-simple.

I would go even further and reexport GHC.Integer from base as well. We now
have that capability with Cabal's reexported-modules field[1].
