            Log:
            test if cups-browsed can access /root/.cups/lpoptions

A recent cups + selinux-policy testing revealed that SELinux prevents
the cups-browsed processes from accessing the /root/.cups/lpoptions
file. The TC reproduces the situation.

In order to support the cups-browsed ability to access the lpoptions
file, I believe that SELinux policy should allow the access. Either
file context patterns need to change or an appropriate policy rule
need to be added. The TC looks for these changes.

The TC covers RHEL-47401.
