Right, that was copy&paste typo.

Either that or we can add short description to the test structure and
pass TST_EXP_FAIL(..., "faccessat2() %s", tc->desc)

At least some cases would be better with description, for instance for
the euid test the description should be something as
"with AT_EACCESS and unpriviledged EUID"
