Update build toolchain to the use of docker…

… for integration tests.

- Update circle.yml to start the docker daemon listening on TCP (to be
  able to talk to it from the container running test-integration)
- Update script/test-integration to prepare the use of go-check
- Update Makefile in order to run less "binary" target and setting up
  the right environment variable for the builds
