Fix corosync 3.x startup failure on SLE 16.0 (#464)

Fix corosync by omitting invalid config options.
Corosync 3.x (shipped in SLE 16.0) rejects crypto_cipher, crypto_hash,
and secauth when transport is udpu, causing corosync to exit with code 8
and pacemaker to fail on its dependency.
These options are safe to omit because they were never functional with
udpu transport — corosync 2.x silently accepted them but only supported
encryption on multicast (UDP) transport. Cluster traffic was never
encrypted with udpu, so removing these options changes no runtime
behavior. Similarly, rrp_mode (removed in corosync 3.x) had no effect
with a single interface.
The version conditional preserves the existing config for corosync 2.x
(SLE 12 SP5, SLE 15 SP4/SP5) and only omits the options on 3.x+.
