std: Ignore a flaky std::comm test

This test relies on the parent to be descheduled before the child sends its

Add requirements of TotalEq and TotalOrd

Clarify that TotalEq needs an underlying equivalence relation and that TotalOrd
needs a total ordering and specifically named the required (and sufficient)
attributes.
