Problem: pulp_installer devel role CI is failing on CentOS 8 Stream

with a module metadata error for the dependency criu.

Solution: Ignore errors when ansible reports the distro OS as
8.1. We will remove this once CentOS 8.2 is GA, and this only affects
the devel role, so a workaround like this will hopefully be palatable.

fixes: #6509
