nptl: Fix abort in case of set*id failure [BZ #17135]
If a call to the set*id functions fails in a multi-threaded program,
the abort introduced in commit 13f7fe35ae2b0ea55dc4b9628763aafdc8bdc30c
was triggered.
We address by checking that all calls to set*id on all threads give
the same result, and only abort if we see success followed by failure
(or vice versa).
