The shellshock callback is targets `os.StartProcess()` and checks the environment variables against a list of regular expression provided by the backend rule. When matching, the call is aborted and the request is blocked.

New Feature - (#142) RASP: add Shellshock protection support. This protection is currently attached to `os.StartProcess()` which is the common function of the Go standard library to execute a process. This protection can be configured at <https://my.sqreen.com/application/goto/modules/rasp/details/shellshock>. Fixes - (#145) In-App WAF: always recover from panics as this in the way the `reflect` package handles usage errors. - (#144) Backend client: avoid dropping HTTP traces in case of `Host` header parsing errors.
