THRIFT-932. hs: Haskell tests need to be run through 'make check' (and probably 'cabal check') too

Tests are now self-contained and correctly exit after running. There's a single run script which has improved error messages and defaults to the thrift binary compiled in the current source directory instead of those in PATH. And as a bonus hooks both cabal check and running the tests to make check. 

Patch: Christian Lavoie
