Andy Lutomirski c7ca0b6145 Revert "x86/ptrace: Prevent ptrace from clearing the FS/GS selector" and fix the test 
This reverts commit 48f5e52e91.

The ptrace ABI change was a prerequisite to the proposed design for
FSGSBASE.  Since FSGSBASE support has been reverted, and since I'm not
convinced that the ABI was ever adequately tested, revert the ABI change as
well.

This also modifies the test case so that it tests the preexisting behavior.
