[MSan] Simulate OOM in mmap_interceptor()

Summary:
Some kernels can provide 16EiB worth of mappings to each process, which
causes mmap test to run for a very long time. In order to make it stop
after a few seconds, make mmap_interceptor() fail when the original
mmap() returns an address which is outside of the application range.
