ceph.spec.in: add ceph-libs-compat

Added a ceph-libs-compat package in accordance with Fedora packaging
guidelines [1], to handle the recent package split more gracefully.
In Fedora this is necessary because there are already other packages
depending on ceph-libs, that need to be adjusted to depend on the new
split packages instead. In the mean time, ceph-libs-compat prevents
breakage.

ceph.spec.in, init-ceph.in: Don't autostart ceph service on Fedora.

This patch is taken from the current Fedora package and makes the upstream
ceph.spec compliant with Fedora policy. The goal is to be fully compliant
upstream so that we can replace current Fedora package with upstream
package to fix many bugs in Fedora.

Addition from Dan Mick <dan.mick@inktank.com>:
Do this for RHEL and Centos as well, since they surely will benefit
from the same policy.   Note: this requires changes to
autobuild-ceph and ceph-build scripts, which currently copy
only the dist tarball to the rpmbuild/SOURCES dir.

ceph.spec.in: Obselete ceph-libcephfs (not libcephfs)

I am guessing that because it was a sub-package libcephfs was mistakenly
used instead of ceph-libcephfs.

ceph.spec.in: No version on ceph-libs Obsoletes.

If we are installing with the new package structure we don't ever want the
new package to co-exist with the old one; this includes the mistakenly-
released v0.81 on Fedora, which should be removed in favor of this
version.

ceph.spec.in: Obsolete all older versions.

Now this changeset can be used on all current ceph releases that already
have the package split.

ceph.spec.in: tests for rhel or centos need to not include _version

rhel_version and centos_version are apparently the OpenSUSE Build
names; the native macros are just "rhel" and "centos" (and contain
a version number, should it be necessary).
