rawhide users: Do this now if you want to stick with F26 and not F27

[Kalev Lember]

Now that F26 is branched off from rawhide, I know many developers
(including me) want to stay with F26 instead of F27 to make sure we are
testing the upcoming release. By default, everyone who has rawhide
installed stays on the F27 train.

Here's how to switch to F26:

$ dnf distro-sync --releasever=26
