Uses/cabal.mk: Change the way we act on cabal.project files.

Instead of moving the original project file into a temporary location,
employ cabal.project.local for Ports-related adjustments.

This implements an idea that upstream cabal.project files shouldn't be touched
by Ports framework. If needed they can be patched by the port maintainer directly.

Adapt existing Haskell ports to this change.
