Fix futex_benchmark.
- Fix definitions of Futex* wrappers.
- Correctly handle glibc syscall() (which returns -1 and sets errno instead of
returning the raw syscall return value).
- De-parameterize FutexWaitBitset, which was apparently intended to test with
deadlines of between 0 and 100000 nanoseconds after the Unix epoch, but was
broken due to the preceding two issues.
- Use wall time to measure the durations of tests that are expected to block
(and thus stop accumulating CPU time).
- Require 5s for all tests to improve robustness in the presence of sentry GC.
- Remove FutexContend and FutexContendDeadline; it's unclear what these are
supposed to measure, given that (1) FutexLock is unrealistically inefficient
and (2) the benchmark rewards slow scheduling (since this reduces
contention).
