Fix breakpoint_set_restart test for Windows

[amccarth]

Summary

When run with the multiprocess test runner, the getchar() trick doesn't work, so ninja check-lldb would fail on this test, but running the test directly worked fine.

This replaces the getchar() call with an infinite loop.

Thanks to Pavel for the insight.

You may remove iostream since getchar is no longer needed.

Done since getchar actually comes from stdio.h anyway.
