Subject: [PATCH] selinux: Drop user_namespace create allow rules
Those are incompatible with current el9 kernels. I introduced them
upstream with commit 62059058cf24 ("selinux: Fix user namespace
creation after breaking kernel change"), in turn as a result of
kernel commit ed5d44d42c95 ("selinux: Implement userns_create hook"),
but on current el9 kernels (which lack the hook) they result in
failures such as:
Failed to resolve allow statement at /var/lib/selinux/targeted/tmp/modules/200/passt/cil:103
Failed to resolve AST
/usr/sbin/semodule: Failed!
