Thanks for reporting.  This was a limitation in strace, fixed by commit
v4.14-195-g05ac490cc79e2369a60da23e696b67fcd6012762 that replaced old
-eread=/-ewrite= implementation with a new bit set based one.

I think that if a test hits a bug, the first idea should be to fix the bug,
not to workaround the bug in the test.
