kola: Update SELinux file context

vasd policy was removed from SELinux policy [1][2], so we update
our test against another component, preferably a more stable one.
I think "pam_shield" is a good candidate.

Closes coreos/rhel-coreos-config#92

[1] fedora-selinux/selinux-policy#2923
[2] https://issues.redhat.com/browse/RHEL-116512
