Revert "x86, bts: reenable ptrace branch trace support"
This reverts commit 7e0bfad24d85de7cf2202a7b0ce51de11a077b21. A late objection to the ABI has arrived: http://lkml.org/lkml/2009/6/10/253 Keep the ABI disabled out of caution, to not create premature user-space expectations. While the hw-branch-tracing variant uses and tests the BTS code.
