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).
