Install master's version of an RDO keystone

RDO isn't moving for approxximately 1 week new packages into
current-passed-ci.  This blocks Sam's keystone bootstrap patch.

To unblock this, we temporarily have provided copr built RPMs
based upon the srpm from RDO and keystone-master tarball.

TrivialFix
