common-ha: explicitly set udpu transport for corosync

On RHEL7 corosync uses udpu (udp unicast) by default. On RHEL6 the
default is (now) udp multi-cast. In network environments that don't
support udp multi-cast this causes the ever growing lists of
[TOTEM ] Retransmit errors.

Always specifying --transport udpu is thus a no-op on RHEL7.

Using the same transport on both RHEL6 and RHEL7 may (or may not
give similar behavior and performance--it's hard to say.

It remains a mystery why things have always worked on RHEL6 prior to
now. Further investigation is required to uncover why this is the
case.
