etc/dists: get rid of many useless configs

First, there's no need to have config like centos-5.conf, because
vzctl will find centos.conf. It only makes sense for old distro
versions, so clean up configs to only have ones for such old
versions. Now, we don't have to add things such as CentOS 6
(which we were always forgetting anyway and, as described above,
it was not needed because a generic versionless .conf was used).

Second, remove:
* rhel-3.conf (same as centos.conf so let's use it)
* sles.conf (same as suse.conf so let's use it)

Also
* fix longer-than-80-characters lines while at it
* merge a couple of targets
* provide generic versionless rhel.conf
* targets are now alphabetically ordered (moved arch:)

Should have no visible effect (or so I hope).
