Test: CTS: update corosync fail patterns

We were looking only for attrd's connection to corosync dropping,
but if the CIB exits first, attrd could report losing its connection
to the CIB instead, and exit before it notices corosync gone.

Also consolidate some other patterns, and ignore cib_rw errors.
