Fix the platform:fedora bindep entry in community.kubernetes collection

We wan to change this to use the epel bindep profile instead, possibly like:

kubernetes-client [epel platform:rpm]

[pabelanger]

from what I see, kubernetes-client isn't packaged for centos, and doesn't exist in epel. Or I might be looking in the wrong place.

oh right, I forgot, this was in some fedora-specific repo.

It makes sense that we wouldn't support it, but I still don't know what would mean for the metadata.

Kinda leaning towards just deleting that line, since none of our images are based on fedora anymore.
