[travis-ci] Fix some build breakage (#130)

Split cabal install into two invocations. Cabal seems to not handle the 'cabal-version' constraint correctly, and ends up ordering the packages to install in the wrong order.
Installing Cabal separately first, and then all other packages, seems to work around the problem.
