build/ops: rpm: provide files moved from ceph-test

d7b493a7108a68302bc0f48337bf3c253a720266 moved three binaries from the
ceph-test package to other packages, causing trouble with upgrades in
test lab environments (users typically do not install the ceph-test
package).

While the original upgrade troubles have already been addressed, RPM
has a "Provides" mechanism for easing the pain, so it makes sense to
use it.
