Title: Obfuscate securely exported shell variables

If the shell variables to export begin with `SECURE` such as:

```bash
export SECURE FOO=bar HELLO=world
```

The `SECURE` variable is stripped and the command is executed normally except that it's echoed in a way that hides the values from prying eyes.

```bash
export FOO=XXX HELLO=XXXXX
```

The [secure env pull request](https://github.com/travis-ci/travis-core/pull/45) on travis-core has been updated to prepend secure env configurations with `SECURE` so they're properly hidden by the worker.
