[PATCH] [asan] debug_mapping.cc should also pass when the leading digit is hexadecimal.

[Daniel Sanders]

I don't mind only changing the SHADOW_OFFSET expression since that fixes my test failure but I have to ask:
Does it really make sense to 'Printf("SHADOW_SCALE: %zx\n", (uptr)SHADOW_SCALE)' in asan_rtl.cc and expect the output to be decimal in the debug_mapping.cc test?
