Reworked custom redhat version. Complete version is now part of library
names. Libraries are not recommended for any third party application.
They are still required for bind-dyndb-ldap only.
Version of named changed, only suffix -RH is appended to upstream
version. Therefore dig would not contain version
9.6.11-RedHat-9.6.11-1.fc34, but only 9.6.13-RH. Version of fedora build
have to be obtained from rpm -q bind.
Version is now part of library names, bind-libs-lite was merged to
bind-libs. bind-dyndb-ldap needs whole bind, no point to offer smaller
library set just for its dependencies.
Updated also named(8) manual page to match current state of SELinux.
