Updated Scripts for setup new dev environment

[fawadasaurus]

I setup a new dev environment and wanted to get the project running on my OSX machine. I installed a fresh Linux VM and was able to run make build and make test with this setup.

I encountered one test failure. I don't believe this failure would only impact me as the oci_spec default for environment variables sets 2 environment variables. So I set the

impl Default for Process {
    fn default() -> Self {
        Process {
....
            // Sets linux default enviroment for binaries and default xterm emulator
            env: vec![
                "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin".into(),
                "TERM=xterm".into(),
            ]

Thanks for fixing this bug! I just realized that our build pipeline is not set up correctly to fail when the make test- fails...

I can try to address that as well in this PR if you would like.

that would be nice! I briefly looked into it with #682 , and suprisingly found that cross test returns status code 0 with a test failure.

Can you please add libssl dep to cross/Dockerfile_* as well?
