Revert osie because the latest version broke tink-worker installation

As I explained here
https://github.com/tinkerbell/sandbox/pull/66#issuecomment-803009169 the
current OSIE on master broke how tink-worker gets installed in sandbox.

For a series of bad habits the PR got merged even if e2e tests are
broken leaving sandbox/master to a not working state

This commit reverts OSIE back to a fully operational version
