Reduce kyverno background controller CPU from 7 to 6 on rh01 (#7665)

Based on usage data, it peaks at 5 so reduce it to 6, keeping a buffer
of 1. The main reason for this change is to allow us to align kyverno
configuration of all the clusters with prd-rh01, which is where the
config was tuned for highest load. All the clusters except rh01 have
workers of 8 CPU so a 7 CPU pod does not fit on them. Reducing it to 6
will make it fit and allow us to have the exact same config on all the
clusters which will be done in a follow up change.
