Changing the file name of the archive file...

... to `nupic-${TRAVIS_JOB_NUMBER}.tar.gz` instead of `nupic-${TRAVIS_BUILD_NUMBER}.tar.gz`. This will enable archives for each part of the build matrix (python 2.6 and python 2.7).
Removing duplicate context in S3 path

https://s3-us-west-2.amazonaws.com/artifacts.numenta.org/artifacts/numenta/nupic/ --> https://s3-us-west-2.amazonaws.com/artifacts.numenta.org/numenta/nupic/
Missed a file name change, changed the name of the tar file.

From nupic-XXX.X.tar.gz to build-XXX.X.tar.gz because it's already going into a directory called 'nupic'.
