Hmm, shouldn't we also ignore stderr if mkfifo fails?

Hmm, probably; but I haven't encountered that issue.  Is it documented
unclearly, or implemented wrongly, that an exit status of 77 does not
override a mismatched stdout/stderr with AT_CHECK?

The implementation is correct. First at_fn_check_status exits if the test's exit status 77. Then at_failed is checked and at_fn_log_failure is invoked if it is true, but at this point we already exited.
