[XRay] [compiler-rt] Fix format string; sanitizers' internal printf() doesn't support %ld.

Summary:
Getting rid of the distance number altogether because:
- a person knowledgeable enough to know what the message means will also
  know how to do hexadecimal math (with the help of a calculator)
- numbers outside INT_MIN - INT_MAX are hard to comprehend anyway

This unbreaks the case when you dynamically link a library with XRay and
it exits pre-main() with a not very informative static string.
