Fixed the OS Variable on initOS

[salehparsa]

The initOS introduced variable OS but it was not working because of the fact that we haven't used${os}and we used $(os)

It caused the installation breaks and doesn't work at all:

./hack/install.sh: line 37: os: not found
./hack/install.sh: line 42: os: not found
OS '' not supported!

The propose of this Pull Request is to have a quick fix for this issue
