manifests: add selinux-workaround.yaml for >= F41

Recent changes in the SELinux policy have broken a lot of our code.
Revert the affected domains back to permissive mode so we can
continue to build and test `releasever >= 41` until
fedora-selinux/selinux-policy#2257 merges
and the domains are reverted upstream or until the issue is resolved
altogether.
