bosh create-env fails on Mac due to bosh-alicloud-cpi/packaging script setting GOROOT

[Amit-PivotalLabs]

I believe the following lines may not be necessary:

https://github.com/cloudfoundry-incubator/bosh-alicloud-cpi-release/blob/dcd22b97b48eb2569fd74994a92d6d9226853537/packages/bosh-alicloud-cpi/packaging#L13-L16

Especially given the golang/packaging script says that if you're on Mac, you need to install Golang yourself:

https://github.com/cloudfoundry-incubator/bosh-alicloud-cpi-release/blob/dcd22b97b48eb2569fd74994a92d6d9226853537/packages/golang/packaging#L17-L20

Those lines assume my $GOROOT is /usr/local/go which is not the case since I installed Golang with Homebrew, which I suspect is quite common for most Mac users with Golang. I deleted the 4 lines, create a dev release, and was then able to proceed.
