hybrid_clock: restore SleepFor in WaitUntilAfterLocally

This seems to have gone missing from commit f2d96437c. The end result is a
busy loop, which was probably unintentional. I also removed the loop, which
seemed unnecessary with the SleepFor.

To test, I wrote a small program that scanned a table at Now() + 10s, after
setting --scanner_max_wait_ms to 10000 (default is 1000). Although the wall
clock time was the same, the cycle count was far higher per perf stat.
