Subject: [PATCH] test(xcat-core): capture CodeReady Builder setup that ignores
 RHSM on RHEL

On a RHEL node, Red Hat Subscription Management owns the CodeReady
Builder repository as codeready-builder-for-rhel-<major>-<arch>-rpms.
enable_crb.sh only asks dnf for the crb and powertools ids, so it cannot
enable the repository on RHEL and go-xcat then fails to resolve its
dependencies.

The new bats cases stub subscription-manager, dnf, rpm and uname. The
two RHSM cases fail on the current script. The EL9 crb, EL8 powertools
and dnf failure cases pass on it and keep that behaviour fixed.
