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

Summary:
Previously the CHECK directive for SHADOW_SCALE only matched decimal digits
causing it to match '7' on x86_64 instead of the whole value.

This fixes a failure on mips-linux-gnu targets where the leading digit is 'a'.
