hook: Replace broken ad-hoc implementation to get envvars
In the `hook` package we have an ad-hoc implementation to retrieve an environment variable's value from an array. This implementation has two problems: - It retrieves the first value instead of the last value as would be done by `os.Getenv()` in case the environment variable is defined multiple times. - It can segfault in case the environment variable doesn't have an equals sign in it. Fix both bugs by instead using `env.ExtractValue()`. Changelog: fixed
