Remove pipefail sets as they only work in bash

Fixes a new error introduced with https://gitlab.com/gitlab-org/quality/gitlab-environment-toolkit/-/merge_requests/121. The pipefail setting is only available specifically in bash where as Ansible is running commands via sh.

Rather than having to remember to run specific commands specifically in bash we should elect not to follow this rule. We may also not always have bash to rely on in the future depending on OS. The pipefail behavior is optional by design and as such we should leave that decision up to the developers.
