conformtest: Fix typo in CLK_TCK condition

[Joseph S. Myers]

One failure in the conform/ tests for XOPEN2K is the expectation of
CLK_TCK.  That symbol was removed in that version, but the expectation
uses "!defined XOPEN21K" where it should use "!defined XOPEN2K", so
wrongly expects it in that version.

I've committed as obvious this patch to fix that typo in the
expectation.  Tested x86_64.
