Upgrading go buildpack to v1.0.1

Upgrading to latest stable version of go buildpack
 --Buildpacks Team
it seems like you specified the wrong file path when you ran 'bosh add blob ...'

we see
```
Building buildpack_go...
  Final version: Package `buildpack_go' has a glob that resolves to an empty file list: go-buildpack/go_buildpack-offline-v1.0.1.zip
```

when creating a release.

We'll try fixing the blobs.yml by hand, but if it does not work, we suspect you will need to re-add the blob and resubmit the PR
