[PATCH] c/r: prctl: Move PR_GET_TID_ADDRESS to a proper place

[Cyrill Gorcunov]

During merging of PR_GET_TID_ADDRESS patch the code
has been misplaced (it happened to appear under PR_MCE_KILL)
in result noone can use this option.

Fix it by moving code snippet to a proper place.

Andrew, I think it get misplaced during merging (the former
patch I sent has this snippet at the proper place). I noticed
this problem only when found that our test suite swears at me
with futex test case.

Anyway, there is nothing critical in this issue, it behaves like
someone has disabled PR_GET_TID_ADDRESS.

The patch is on top of v3.5-rc2
