`hs-blake2` currently wrongly depends on `pkgs.b2` which is an application
for backblazes storage service. This patch overrides it to link against
its correct native library `pkgs.libb2`.

This commit implements the changes necessary to start up a graphite carbon Cache
with twisted and start the corresponding graphiteWeb service.
Dependencies need to be included via python buildEnv to include all recursive
implicit dependencies.
Additionally cairo is a requirement of graphiteWeb and pycairo is not a standard
python package (buildPythonPackage) and therefore cannot be included via
buildEnv. It also needs cairo in the Library PATH.
