  [libcxx testing] Remove ALLOW_RETRIES from sleep_for.pass.cpp

Operating systems are best effort by default, so we cannot assume that
sleep-like APIs return as soon as we'd like.

Even if a sleep-like API returns when we want it to, the potential for
preemption means that attempts to measure time are subject to delays.
