[BeforeSuite] [FAILED] [8.752 seconds]

We run tests when building ssh3 package. Our build environment does not have access to Internet for security and reproducible builds purpose. Tests for 0.1.4 were OK but tests for 0.1.6 fail with:
```

Looks like it tries to run `go install github.com/francoismichel/ssh3/cmd/ssh3-server` since commit 53d7264847ba5d6d86b97644636b09bf8cbd388a.

Maybe it's possible to make tests work without access to Internet? (Without `go install` basically.)

It's pity to disable integration tests run.

Start with integration_tests/ssh3_test.go, especially the BeforeSuite setup around lines 59 and 90, and reproduce the Ginkgo command shown in the report in an offline environment. Trace the server setup and the go install invocation introduced by commit 53d7264847ba5d6d86b97644636b09bf8cbd388a; done means the integration suite runs without Internet access and does not install the server from the repository.
