[RFE] improve messaging when using rpm-ostree install + SELinux disabled

[miabbott]

The output from rpm-ostree when trying to install a package and SELinux is disabled is cryptic. See #971 and this thread on the Silverblue forums - https://discussion.fedoraproject.org/t/install-a-rpm-package/2163/

Could the error/messaging be improved here?

I'm guessing you meant to paste another link here? :)

@jlebon thanks for the eyes...updated original comment.

So I can understand (because I've been bit by this)— would you change the messaging to say "SELinux must be enabled to use rpm-ostree"?
