packaging: include ceph_perf_objectstore

The /usr/bin/ceph_perf_objectstore file is installed by default. Prior
to this commit it was missing from the packaging. This caused the RPM to
fail to build in mock.

Add ceph_perf_objectstore to the "ceph-test" RPM and Debian package.

If we end up developing further ceph_perf_* utilities, it would make
sense to glob them all with a wildcard, similar to what we are doing
with all the ceph_test_* utilities in ceph-test.
